I'm a zombie-flick fan. =) I'll admit that readily, but it took me several months before I finally saw this movie because I was so utterly disappointed with the first one. In the first movie they had these incredibly annoying, flashing video game-sequences or something cut into the movie - probably to save money since that way they only had to make half a movie.
None of that crap here thank god! This was actually a pretty decent horror movie - with zombies! I say decent but for a zombie movie it was pretty darn good. The special effects were better than average for a zombie movie, so was actually everything about this movie. Even the zombies stagger better in this one than usual! The story has a good pace with plenty of "plot" and action through-out the movie, and the acting was surprisingly good. And with that I mean that some of the actors were actually really good and the others decent!
My verdict is that this movie is in no way a future classic by any means, but it is a decent horror movie and as far as zombie-movies are concerned - definitely a trend-breaker in the sense that it falls into the "decent"-category as a whole. Ususally zombie-flicks are either really good - or quite the opposite. So if you are looking for a decent horror movie or a good zombie-movie - see this one. But avoid the prequel at any cost...
