i LOVE zombie/apocalypse type movies in general. some that i've seen and liked:
dawn of the dead (new one)
land of the dead
all resident evil movies
28 units of time later series (might even rewatch those soon)
i am legend (that COUNTS!)
though i can't seem to think of others i've seen, recommend away!!! I'm jonesing for some zombie action! Note that i'm looking for something that attempts to take itself seriously to some degree. For instance, i loved army of darkness, but that's a bit too b-grade / goofy for what i desire.
RECOMMEND AWAY NETIZENS!
