well despite what i said in this thread before i saw the movie, i actually thought this was good, one of the best King adaptations that i've seen. the ending, while grim as fuck, really seemed like a Stephen King ending to me, and it works better in the film to have an ending like this than the ending that was in the story. as for the people talking about cheesy acting, i have to ask, have you ever read the story? the characters in it were pretty over the top in the first place, so the acting should be as equally over the top. also, the story and the movie were meant to be throwbacks to the old 50's B-movies, so the acting suited it imo. the special effects could have been better, but it was pretty low budget, so that isn't surprising. and once again it fits into that B-movie motif.
edit: has anyone watched the B&W version of the movie on the DVD? if you like the 50's motif, this really gives it that true feeling.
