This is not a horror movie.  This film does not compare well with horror movies.  This is an action movie with zombies.  It compares very well with other action movies.  Starting where Resident Evil ended, the bullets start flying and the zombies start chomping immediately (do watch RE before this one).  Although the script is hardly award winning, the movie delivers much more than you would reasonably expect from a video game based zombie movie.  The actors are capable enough, and even if you find them stiff and generic, it's okay - most of them don't survive very long.  Sadly, the comedy relief guy isn't funny at all and he does survive the whole movie.  Also, the martial arts and special effects are good overall (except for the CGI Dobermans which are awful).  Somehow the film avoids being predictable and sets up the last part of the trilogy nicely.  Whether or not you've played the video game (I haven't), Resident Evil: Apocalypse is sure to satisfy cravings for a fast-paced action movie with sexy, gun-toting, butt-kicking babes if you can forgive a few rather forced script elements (like main characters strolling through a graveyard totally oblivious to the risk this involves during a zombie uprising!)
