Review: I get to the cinema every week or so, and regularly check out this site, but never before have I felt compelled to comment on a film.To my all time list of shockingly bad films - Last Man Standing, Spawn, The Bone Collector - I can now add the drivel that was 'Hollow Man'.From the awful opening titles - a ridiculously over-long run through of cast and crew put together with alphabetti spaghetti - through to the insulting finale - a world record number of cliches and some of the most absurd dialogue and acting to have ever made it to cinema - this film is dismal, and only the impressive computer graphics keep you from walking out long before the end.This isn't just my opinion - it was that of my friends, and everyone around us. When large sections of an audience are laughing and groaning during and after a serious thriller, its clear that the film is hopeless.Not only that, it was sick too. The director took the action beyond the bounds of realistic fare for a violent film, and into the realms of an over the top blood soaked B-movie. It's difficult not to imagine the director as some sort of dirty old man, because the extent of the invisible man's forays out of the lab and into the outside world extended only to two attempts at having a feel of some breasts. Perhaps sex could well be the first thing on a bloke's mind if made invisible, but aside from the aesthetic pleasures of the ladies involved, it hardly makes entertaining cinema.[spoilers follow]Get past the films sick exterior, and things are even worse. Whilst Kevin Bacon does a good job of acting increasingly twisted as 'hollow man', the rest of them - perhaps handicapped by a dire script - do an even better job of being hollow cast. One long time member of the team is found strangled in a locker by the invisible man, "He's finally snapped" shrugs one colleague without a hint of emotion. This is par for the course, and the lab team swing between sheer terror and complete indifference with such speed that you wonder how they got into acting. They pad their way through the lab corridors terrified, guns poised, but then seconds later one of the crew skips happily off back down the corridor to get blood for a hurt colleague. The lead female treats the invisible man with courtesy and good humour even after he's insulted and abused her, and there seems to be little reaction to his breakouts, even after he drowns the Pentagon chief, "He drowned in his pool last night" reports the same female, spectacularly failing to put two and two together.The script is littered with this kind of badly acted pedestrian dialogue, and the rest is just an A-Z of film cliches, which get laid on thicker and faster as the film progresses to the point of complete disbelief and amusement at the end.The 'eureka' moment at the computer, the female undressing at the window, the looped security video - the list really is endless - the predictable disregard for strength in numbers, the decision not to kill the two main stars but just put them in a place of probable impending death and leave them to their own devices, the almost-dead good guy appearing out of nothing to save the woman, the bomb and ubiquitous countdown timer, the fireball explosion which just burns up before reaching the heroes, the falling lift which just stops before hitting them, and more than anything else, the immortality of the bad guy.The invisible man is burnt to a shred with a makeshift flame-thrower, electrocuted, whacked round the head with a bar which had just sliced straight through one of the lesser actors, and then having apparently survived the explosion, fireball and total destruction of the labs, has more than enough life left to climb up through the fireball for one last pop at the films heroes - by which stage the disbelieving audience are cringing and looking at their watches.That this exceptionally bad film actually made it to the cinema is astounding. Even the name of the film is as hopeless as the movie itself, and not even impressive special effects come anywhere near saving this one, which should be avoided at all costs.

Review: Journey to the Center of the Earth is the story of some tourists of Hawaii, three of them siblings, and one of them a young British nanny babysitting a dog. When the siblings accidentally drive off in their jeep with the basket of dog biscuits, the nanny follows them (it might've just been safer to purchase more) all the way to the cave the siblings intended to explore (I guess). For some reason, they actually go in the cave and then, when the place starts caving in, they try to get out to no avail, except for the six-year-old sister who they tell to go get help. Meanwhile, the more they move around in the cave, the more they continue to plummet further and further towards the earths cavernous core. And behold, it is here where they find the City of Atlantis and its bizarre alien habitants who are living under the oppressive rule of one alien that doesn't want them asking to many questions about the worlds external to their own.I see that Rusty Lemorande, the named director of the film has provided comments on this film, in which he explains that part of latter half of this film is actually the sequel to Alien in L.A. Well, whatever it was, it was an amazingly cheap movie that I would rank only slightly higher than City Limits (a 1988 sci-fi film also made on a non-existent budget) because at the least ending of this dreadful piece of mostly incoherent film-making that cuts corners where it can aims for some humor and amusement in the last 20 minutes when we finally see what life is like in the alien world at the center of the Earth. I also give it a two star rating rather than one because it was at times, funny, even if only in its subtleties. For example, the aliens asks the British girl if she's an alien and she explains that the Ministry should be sending her work visa shortly. Or when the alien girl finds Bryan and explains that he is in the city of Altantis and he mistakes this for Atlantic City, New Jersey. Little things like that make the idiocy of the first hour or so tolerable. Imagine how great the film could've been though if they had 1) actually intended to make it, and 2) actually had money to make it.I do like how in the end, no one wonders what happened to the little sister who was sent away in the beginning to get help. She'd just be wandering around the Hawaiian caves and not too far from the erupting volcano, mind you. Question: is it a negative review?

Review: There is no doubt that this film has an impressive cast but unfortunately this doesn't help with the major downsides to the movie. I never understand why directors ask actors/actresses to use accents not their own when it is obvious to everyone they can't convince. Fiennes just can't do Irish and Fitzgerald isn't much better at Russian. When the voice is wrong then no matter how good the acting the character will never be convincing. As the for the major problem....the plot....was there one? I guess there was some sort of storyline involved but it was so full of holes that I just couldn't wait for the film to end...it was ridiculous. Save 90 minutes of your life and don't watch this movie! Question: is it a positive review?
