Last movie I saw was The Mist last weekend. It's based on a story by Stephen King, so I had high hopes, but the writing for the movie was pretty disappointing. Every plot development just seemed so forced, as if they wrote a story separate from the book and had to go back and quickly edit some things in.

The explanation for the mist was equally forced and anticlimactic, mentioned once with no build up or development and then forgotten. The creatures in the mist were not remotely frightening and their inability to break glass or damage buildings or vehicles was frustratingly unbelievable. The ending was decently unexpected and a good twist, though also seemed kind of haphazardly done like the rest of the writing.

Overall: 5.5/10 (I couldn't decide between a 5 or a 6)

EDIT: I should qualify that I was a bit drunk when I watched this, but still quite lucid.
