I remember hearing that the original Evil Dead is the worst of the trilogy.
I don't know, I thought it was pretty good. Sure it doesn't have the slapstick of the second movie or the shear joyous insanity of the third, but it's supposed to be a straight forward horror flick, and it succeeds completely. The blood flows, the makeup is great, the special effects are fun, and there were a couple of times when I jumped even though I knew what was coming.
Sure, most of the acting is over the top and bad in the only way that newish actor can act, but that's part of the charm. Most horror movies now feel too slick and polished. I like how Evil Dead is gritty and grimy. The way it's shot feels more real, more intimate.
The only thing that kind of bothered me is that it's the women who get possessed first. Why is that?
