This film starts as a high tension sci-fi thriller, but inspite of that tension, it is not that good. The too eleborate introduction to the film promises more story than is needed. Halfway the film drops into an unimaginable zombie slasher causing another drop in level.
In some future a big company has a big underground laboratory for secret experiments. Something does wrong, the AI defence system takes over and a small group of soldiers has to enter the city to shut down the main computer. Anderson apparently could not choose a genre and he goes from sci-fi thriller to gory horror to drama to action, coming to an unbalanced, not too well acted and story-wise uninteresting film.
I guess this film is for people who feel like some mindless action.
