Movies based on computer games generally aren't well respected, but just because they aren't high art doesn't mean they can't be highly enjoyable. The only catch is that you need to be a fan of computer games to appreciate them. Resident Evil: Extinction is the third movie in the massively popular Resident Evil franchise, and it's probably the best one yet.
Between Resident Evil: Apocalypse and Extinction, the zombie-creating T-virus has spread far beyond the doomed Raccoon City; now the human race is almost extinct (hence the title). When a convoy of survivors meets up with the genetically-altered Alice, the shadowy Umbrella Corporation does everything in its power to take them down and reclaim her; but Alice isn't giving up without a fight...
Resident Evil: Extinction is part zombie movie, and part post-apocalyptic survival yarn. The big set pieces use CGI that doesn't look anything like reality, but does look very much like a computer game, which is possibly intentional--since this is a sequel to an adaptation, Resident Evil: Extinction does tend to assume a built-in audience which is already familiar with the various quirks of the franchise. If you're a fan of the games, you'll enjoy the various references to game characters and events; if not, you might feel a bit left out. It's not the best entry point to the franchise if you're a complete newcomer, but if you've seen the other films, it's a hell of a lot of fun. -- Sarah Dobbs
