Mostly, they're just plain old killings. The revelation of the killer is indeed a surprise, but only because his or her identity and motives are so ridiculous that only a lunatic could have predicted them. With the possible exception of the mildly memorable Reese, there are no real characters here. First-time director John Ottman has no sense of pacing or plot. Ideas are started and then abandoned.
Characters disappear for a long time and then turn up again.
The movie meanders for a while, and when you think it's over, it still has a half-hour left. There is no building to a climax, because there is no climax. Finally, we learn who the killer is, we don't care, and the movie finally stops hurting us.
