Overall, it was a pretty good movie. It entertained me, and it had zombie-like people (well, it was actually a virus, like in 28 days/weeks later- but still, that concept of zombies is always awesome). The camera was pretty shaky at times, which was a bit much, and at the end, Jennifer Carpenter, as hot as she is, got pretty annoying with the screams, crying, and hyperventilating. Kind of wish she would have shut up near the end.
Pretty good jumps, some decent little gore parts- so overall, not a bad movie. I would probably buy it on DVD. Obviously no movie is perfect, and everyone will have their own views, likes, and dislikes. If you look at all the other past horror movies, this one isn't too shabby. Look, a movie entertains you, then it did it's job. That's why it's called "entertainment." Just because some jackass on the street says it sucks, and just because it didn't get many "stars," doesn't mean it's a bad movie. Plenty of "bad movies" have entertained the hell out of me- in turn, making them good movies- to me, at least.
