The entire movie led up to this scene (this is just a tiny part of the scene). Mo'Nique played one of the most vile characters I have ever seen. I was captivated by her performance and felt a strange sense of pity for her character.
A scene in Identity when we find out the whole story takes place in this one guys head. Wish I could see that again. Most of the movie sucks. Or at least, hard to watch.
