I haven't read the 1-star reviews before posting this because I didn't want to be swayed by them. My opinion is "Trap" was a great movie. It kept me on the edge of my seat from beginning to end. It had Shyamalan's trademark odd camera angles, odd details that become important and surprises that startle you. Yes, this movie isn't as well done as "The Sixth Sense," but not every movie can be great.
I think the afternoon was well-spent seeing "Trap."
