The Mist

One of the better film adaptations of a Stephen King work. Good cast. Marcia Gay Harden deserves an Oscar for her performance. Her character is only annoying at first, but she is absolutely contemptible by the end of the film. The special effects are decent, if not a little shoddy by today's standards. Though I feel the movie doesn't quite capture the weird horror of the novella, it's still pretty horrifying. The ending is different and, quite frankly, better than the book. (Stephen King is on record as saying he wished he'd thought of it.)
