Cube is a great example of a low budget Sci-Fi horror/thriller film that utilizes its small budget and does something extremely clever with it. The simplicity of the storyline and setting really is the films strongest asset. Six incompatible characters are trapped inside a massive cube comprised of smaller interconnected cube shaped rooms, some of which contain deadly traps. The characters have no idea how they got there, why they are there, or who put them there. But with no food or water they quickly figure out they need to escape and fast. All they have to do to escape is avoid the traps, work out the structure of the cube and try to get on with each other. Unfortunately, it's the latter that proves toughest test. The plot twists are well thought out, and the progressive story of the group battling against the emotional, mental and physical problems they encounter is thoroughly engaging, and the film holds your attention from the first scene to the last. One of the clever things about 'Cube' is the way Director Vincenzo Natali leaves a purposely ambiguous ending to the film, leaving the viewer to decide the true meaning of the Cube.
An interesting concept but the storyline of each character has no time to develop in the film, the acting is poor and wooden, no character is worth a second glance and the overall film is extremely disappointing. Too much is made of the mathematics of the problem (and even then it is a leap of faith to understand what is going on). This is probably based on a Star Trek TNG episode when Picard finds himself in a similar situation with unknown characters but he had the brains to figure it all out.
If you rent it, put it on fast forward to save yourself a lot of time
Quite interesting. Acting a little wooden at times and the end doesn't really give you any answers. I like sci fi and thought it was entertaining enough. My wife on the other hand thought it was a very average film. I don't think I'll be bothering with the sequel though.
