Just watched the trailer... Looks ok. I've seen all the other movies, and it's kind of it's own thing now. Only slightly related to the games in names of characters and the fact there's zombies.
Anyway, I'll probably see this one since I've seen all the others. I've enjoyed them all except part 3. That one was a pile of fucking shit. The others were just mindless popcorn fun really. Hopefully this one will be as entertaining as the last one was.
