Are you able to predict the villain in a mystery movie ?

Me too, guessing wrong in Angels and Demons, I think the villain is from illuminati but actually the bishop, pretty clever story. May be my vision distracted by my memory of the prequel - The Da Vinci Code, in that movie they talk about dark organization and the villain also came from that organization. Sometime my prediction right, for example in the skeleton key movie, even that movie's plot pretty confusing but I know the villain is the past witch that transform into other people's body.

well yes. my guess usually come true. I haven't seen angels and demons yet, but i'll check it out. One movie that i recently got the dvd is pink panther 2. When i first saw the villain, i thought, hmm...this person would make a good villain, could be. But didn't think much of it. turn out correct.

When it is obvious, I can predict. But I rarely discover.

I am not also good in predicting villains. Have you watched the anime Conan? The small detective, there are so many suspects and the main suspect is not very suspecting at all. It comes out that the most kind character in the episode was the suspect! gosh, it's hard.
