us critic - type people are always shaking our heads and telling everyone that movies are n't thrill rides , but i think that " back to the future ii " is one of the few exceptions .
if the original film had the spirit of the 1950s , then this has the spirit of the 80s : full of fights ; chase scenes ; cliff hangers ; special effects ; some detective work ; and of course the vision of the high - tech future .
the film picks up exactly where the first film left off , with doc ( lloyd ) , marty ( fox ) , and jennifer ( elizabeth shue ) travelling 30 years into the future , because something bad is going to happen to marty and jennifer 's kids .
doc tells marty he must take his son 's place at an incident that will cause a chain reaction if marty mcfly jr .
says yes to griff ( wilson - in one of four different roles ) .
whoever said history tends to repeat itself was n't joking , especially when it comes to the movies .
essentially the same chase scene that marty endured in the 50s takes place again in the year 2015 , but it 's not as authentically exciting this time because it is so obviously a parody of itself .
at the end of the situation marty has changed the course of history for the better , and it seems like everything 's copasetic right ?
wrong .
since when do things go according to plan in the " back to the future " movies ?
there are so many minor conflicts and details that effect the plot and the direction of the story i wo n't even bother to list them all .
basically we get to see marty as an old man , his house , his family , etc .
we also go back to an alternate 1985 , and then back again to 1955 , with everything happening so fast the film never stops to catch a breath .
the films ' best aspect is the fact that it actually goes back to the first movie and shows a lot of the action that occurred from another angle .
it 's difficult to convey the sense of wild and zany fun without describing every little detail .
the only thing sacrificed in this film is the suspense .
instead of a grand finale , we get lots of little victories .
by the end everything is back to normal , but something happens that leads to yet another sequel , but it does n't seem gratuitous .
" back to the future part ii " is a really great adventure movie .
it certainly has more originality than other films but it lacks a certain charm that was dominate throughout its predecessor .

while watching " shallow grave , " i found myself periodically noticing thematic similarities to the coens ' " blood simple .
"
both are good films in which several characters , none of whom are the most conscientious to have walked the earth but still are not really evil , indulge in an act of deception that soon necessitates more serious crimes .
the body count rises , and before long seemingly normal people have blood on their hands .
both films are also flawed , but for different reasons .
"
blood simple " is unrelentingly dark and moody , but its characterizations were a little hollow .
" shallow grave , " on the other hand , is nearly flawless for an hour and twenty minutes , and then the filmmakers throw away much of what they 'd accomplished for a more standard , audience - pleasing ending .
the events of the film were sufficiently intense and disturbing that i honestly felt quite troubled by what i was witnessing on screen most of the time , yet there was a slight grin on my face at the end .
as the film begins , we are introduced to alex ( ewan mcgregor ) , juliet ( kerry fox ) , and david ( christopher eccleston ) , a scottish trio living in an apartment in glasgow .
they are all sarcastic and occasionally obnoxious , but other than that they seem like a fairly normal bunch .
a man named hugo moves into the apartment 's remaining vacancy , and the next morning he is found dead of a drug overdose .
juliet is about to call the police when alex discovers that hugo had brought with him a suitcase filled to the brim with cash ( presumably from criminal activities ) .
the three eventually decide to keep the money and cover up the death ; after a drawing of straws , the particularly unenviable task of mutilating the body so as to make it unidentifiable and burying it falls to david , who had been the most reluctant to partake in the scheme from the beginning .
all of this transpires in the first twenty minutes or so of the film , and part of what makes " shallow grave " so brilliant for a while is that i honestly had no idea what was coming next .
other than the obvious question of why they do n't report the death and simply hide the cash , which is not addressed , the plotting and characterization , while sometimes predictable , worked in a way that kept my attention and , on more than one occasion , gave me chills .
i will , therefore , attempt to continue this review in a way that does n't give away too much of the plot .
broadly , the trio are in danger due to hugo 's underworld connections , as two goons search for the money and kill several people in the process .
a police inspector ( ken stott ) is clearly suspicious and visits the apartment , asking pointed questions and trying to unnerve the three suspects by exchanging banal and weirdly humorous bits of dialogue with a junior detective .
david , meanwhile , becomes increasingly paranoid , moves into the attic , and develops an affinity for sharp objects .
director danny boyle effectively creates an atmosphere of mounting tension and suspicion in the apartment , and finally the three seem ready to turn against each other .
while i do not consider myself the " happy endings are automatically stupid " type , i thought that " shallow grave " really should have ended in tragedy - a realistic analysis of the story up to the last ten minutes of the film would indicate that all three characters were probably about to end up in prison , in the mental hospital , or in the morgue .
this could have been accomplished , quite credibly , but then boyle and screenwriter john hodge seem to flinch and opt for a more conventional " caper " ending in which we get a kick out of seeing who outsmarted whom , and nothing more .
granted , this is n't really a " happy " ending , but it 's still pretty light - hearted compared to what preceded it .
i really should n't say anything more about the ending as far as details go , but let me add that it seemed not only shallow and lazy but also inconsistent with the rest of the film and not very believable .
yes , this ending made me crack a smile for a couple of minutes , but ultimately it left me feeling as if i 'd been cheated .
still , " shallow grave " was brilliant
most of the way through , and it does at least meet the minimum requirements for an entertaining thriller , and i am therefore awarding it three stars .
i guess i just ca n't help but think about that fourth star that boyle and hodge let slip away .

summer movies are , by nature , dumb affairs that are usually made for some quick enjoyment and to make money .
wild wild west , the latest will smith affair , follows much the same formula , except that it is dumber and less enjoying than most summer movies .
will smith plays jim west , a black sheriff with a nice line in sunglasses .
he is called by president grant ( kline ) to go on a mission to find out why top government scientists are disappearing .
west is paired up with scientist artemus gordon ( kline again ) and the two track the missing scientists to a legless mastermind , named dr .
loveless ( branagh , with a zany moustache . )
before i pile on with the many negatives in this sorry affair , i 'll give it a chance with the positives .
there 's a nice credit sequence , the production design by bo welch is pleasing to the eye , and the special effects are decent enough .
there 's also a pleasant soundtrack .
buried deep in the dross are one or two amusing jokes . and salma hayek pops up as the female interest , which is always nice to see .
apart from these factors , though , nothing else in wild wild west works .
firstly , there 's little chemistry between smith and kline , who appears to be in it purely for the money .
one would expect zingers passing between the two : none arise .
both of them plod through the below standard plot , knowing that there is a pay cheque waiting at the end .
not even kenneth branagh provides much entertainment
: although he is over the top , the material does n't present much opportunity for branagh to be truly crazy .
therefore , he just comes across as loud as obnoxious .
the only enjoyable performance comes from the sexy salma hayek , who is given so little screen time
it 's embarrassing .
she appears to be in the film to merely show off her body , and be ogled at by kline and smith .
her character also changes at a whim to fit the mechanics of the script , and there is no sense of realism about the character .
the ' humour ' in the film is also very off .
will smith put a little spin to his daft lines in men in black , here , not even smith could save the humour on display .
the script largely boils down to insults that are n't very funny
, and one - liners that barely raise a smirk .
it 's also somewhat racist , although it does n't intend to be , with one scene with jim west trying to wisecrack his way out of a lynching , and actually says slavery is good to save himself .
it 's not a funny scene , and the whole thing comes off rather uncomfortably .
the film also makes the tragic mistake that a man ( in this case kline ) in a dress is automatically unfunny , it is n't ,
but the wild wild west makes this joke even more painful to watch through pure ineptness .
there 's also problems with the plot .
jim west and artemus gordon get caught up in all kinds of sticky situations , but the way they get out of them are always unsatisfying , and rely purely on luck , rather than audience pleasing skill .
plot elements are introduced into the film , and then thrown away just as quickly .
the main piece of the story , a 80 foot mechanical , steam driven spider devised by loveless looks rather impressive , but there 's no particular reason why it should be built .
why not loveless build a great big tank , instead of an ungainly , fragile piece of machinery that 's just begging to be blown up ?
director barry sonnenfeld always has a breezy look to them , with some nice camera tricks , but even this is missing from this stilted affair .
wild wild west could have benefited from sonnenfelds whacked out style of directing , but not much of it is evident , making this film drag out even more .
it 's a sad thing when _ four _ ( credited ) screenwriters , a talented director and a willing star ca n't make a film work , and eventually wild wild west collapses under it 's sexist , mildly racist , unfunny weight .
