I saw the Mist. Do yourself a favor and go see it. This is one of the best horror movies to come down the pipe in a long time. The critics missed the boat, I think, as they often do in the world of the horror movie. It was gruesome and bold, both the monsters outside and the depravity of humans Milgram showed us is on display. It was fantastic... Rachel scraped my arms several times, no one's grabbed on to my arm that tight since I was in 6th grade and watched the fly. Anyone who has bug issues will freak out.
BTW the ending was unnecessary... but what can you do... they were just trying to make it even more horrible.
