I too prefer the first but I did liked the sequel. The first had me screaming at my television, it was night and Summer so not only were my parents kept awake by me screaming at these two idiots but also my neighbors since the windows were opened.
Yeah, I really like the first one. I think the characters are really well developed, plus it was the first time Justin Long was the star of a movie. I did think it left more to the imagination when we didn't see the creepers face though
