Question: Review: Carnosaur 3 is bad... awfully bad. Bad to the point where it is funny. How matter how much I try to convince myself, I just can't believe anyone in this world could find this entertaining for serious reasons. I mean, come on, even the cover is bad! OK, the special effects are absolutely ridiculous. Those "Carnosaurs" are really ridiculous. A scientist tells the soldiers that they move incredibly fast, yet when you see them run, they run at the speed of... an actor in a rubber suit trying to run as much as he can. And the explosions are funny(there is no other word to describe it). At the beginning, a bullet hits a Jeep AFTER a guys says "What was that?"... And the other explosions are also laughable. But the worst thing is the screenplay and the so-called story. You don't expect a good story(or, I don't think anyone renting this movie expects a good movie) but at least the story has to try to make sense. I mean, how hard is it to make a story about dinosaurs killing people at least coherent. Incredibly hard if you look at this. Oh, and if you think that it's easy to makes believable commandos as your characters, tell it to the writers of this awful, awful piece of crap. I mean, what sick human being would make cheap jokes after one of his buddies is dead? And they do lots of it. And if you think that a movie about dinosaurs killing soldiers can only be at least action-packed, WAKE UP!!! This movie is incredibly dull. The carnosaurs(who invented this lame name anyway?) attack(in boring action sequences where you don't see much happening). The soldiers think of how to beat them(in incredibly funny scenes where they try real hard to be serious but can't seem to convince even just one second). So, then, they attack the carnosaurs, but their idea doesn't work(another laughable action sequence). Back to planning(with a few lame jokes thrown in) in another ridiculous scene. And this goes on, and on, and on. And let's not forget the acting which is about as convincing as the special effects... and the story... Oh OK, this movie simply sucks from A to Z. Question: is it a positive review?

Answer: no

Question: Review: I have loved this movie all of my life. It's such an intelligent story also, with plenty of classical allusions. eg. The ship that went missing decades earlier was called the Bellerophon. Well, in classical mythology this was the man who slew the Chimera, a legendary beast composed of two or more other creatures. In FP, Walter Pidgeon is clearly the chimera- himself and his Id monster. I like movies where the writers have clearly credited their audiences with a modicum of intelligence, unlike most modern blockbusters which spend $150m on special effects, but about $1.50 on a screenplay.Cheers Question: is it a positive review?

Answer: yes

Question: Review: Jackie Chan is considered by many film and martial arts movie fans as one of the greatest action stars ever to grace the silver screen and Police Story cemented his reputation as the likely successor to the late, great Bruce Lee. If Enter The Dragon bared the so-called bench mark of Lee's greatness in the 70s, then the same can be said about Police Story and Jackie Chan in the 80s.Forget about the Rush Hour trilogy, or any of his US efforts- the one film that really typifies Chan's excellence, not to mention kick starting his status as a high kicking, bone-crushing kung- fu talisman, as well as his movie career was this, Police Story- the first in a series of successful cop films, set in mainland, present day Hong Kong.I've seen many of his efforts- likewise the US-based Rush Hour, Rumble in the Bronx, The Medalian and The Tuxedo to name- and frankly many of them pale into insignificance compared to Police Story. In those movies, we saw a less 'dumbed down' version of Jackie, of whom didn't get the opportunity to utilise his fighting abilities to the maximum, not to mention the fight sequences were no where as good as those in such efforts as Drunken Master, Police Story to name. The stunts in this movie are extraordinary and are the best featured in any action movie. The shopping mall scene is literally one of a kind and has to be seen to be believed: the flying shards of glass, Chan who is left dangling outside the bus only by his walking stick as a madman frantically drives through the streets of the town, and Chan successfully making usage of all sorts of inanimate objects and prop devices as weapons to fight the bad guys with. Considering he is known for injuring and breaking every bone in his body and putting himself in harm's way, Jackie's persistence in showing his versatility as a stuntman himself by not relying on one, is somewhat of a testament to his reputation as a kung fu expert. Especially as he has the bruises to show for it. Thus, he has proved that he is no one-trick pony when it comes down to devising and coming up with various and clever looking moves.Story-wise, there is not much to discuss but what it lacks in narrative, it makes up with its end-to end action and fight sequences. As for the dialogue, well it's not a really huge aspect of the film- which is why most fans of Jackie's and martial arts films are more interested in action, as opposed to the story.Unlike say The Matrix, there are no wires or CGI, or any form of computer trickery involved. What you see is what you get- and what you get with Police Story is a great Jackie Chan epic, full of action and pulsating stunts.It is miles better than Rumble In The Bronx, Rush Hour and all his other American efforts.Police Story is an excellent film and one I'd definitely recommend to anyone who is a novice Jackie Chan fan, but of whom are unsure which one they should watch first.
