Lots of ACTION, sfx, and attempts to be cool.
The action and sfx are somewhat impressive but mostly pointless; there to distract attention from a really mediocre script.
The attempts to be cool succeed very rarely.
Basically the only REALLY interesting thing about this movie is The Zombie Whisperer, which comes in the last third and is still contaminated by the other three.
Please adjust the grade upward relative to how much of a moron you are.
Grade: D
