Despite decent acting this movie is pretty worthless. if you know anything about computers you'll laugh yourself silly as the makers of the film obviously don't. But, besides the nitpicking the script is just terrible (theres a scene that just consists of the characters realizing their predicament and uttering an expletive - the same expletive no less for about 5 minutes) and the ending is muddled and morally sententious. Not gory enough for gorehounds, not campy enough for b-movie fiends and in general just too boring for everyone else. A decent concept is wasted in the process.
