I enjoyed The Mist. It wasn't fantastic, but it was good and had a point that didn't feel like Swiss cheese.
"The movie builds toward the climax nicely, and you get the chance to get up close and personal with the characters. The feelings of dread and panic are believable... ...Way more important is what the people do to survive and how they cope (or don't cope) with the monstrosities. This is the beef of the movie, and King drives it home well."
