This movie has some really good elements. The dialogue is witty, oftentimes laugh-out-loud hilarious, and the twist on the narration at the end is ridiculously clever (and without a doubt my favorite part of the entire movie). There are scenes that stand out, like when the demon chases the woman by touching people nearby, or the first confrontation between the demon and Denzel Washington's character.The acting, music, and cinematography were acceptable, but not exceptional. The characterization was pitiful if not nonexistent. A lot of the plot was hackneyed and/or easy to predict, so the thriller aspect of this movie lost its impact. I felt it lost a lot of steam near the ending, so it was just tedious waiting for the ending. Many people thought the ending was kind of cheap (I don't have too much of a problem with it). But overall, the cool scenes, the twist on narrative, the witty dialogue; it's just not enough to make this movie interesting enough to recommend.
