Skip it unless you just want to continue the series.

Rating: 3/10 (14 May 2008)

Resident Evil: Extinction, like the previous two, is more of an action movie than a zombie movie. Really, the way they pick off zombies is a lot like the way Rambo kills commies. That being said, the action scenes are decent.
This movie also gets points for an attempt at originality. I'm talking about the "zombie birds" - I've never seen that before. However, it ended up seeming silly, and, more than anything, they just swiped the entire scene's execution from the Hitchcock movie "The Birds." The plot was poor and lacking, and they wasted a bunch of time on characters who went nowhere. Out the 90 minutes of this film, you could probably cut an hour and the plot would be completely unaffected.
The only reason to see this film is if you've already seen the first two and are curious to see where the story is going. Although, don't expect any fulfilling conclusions because they leave the ending open for another sequel.
