I saw Red Eye a couple days ago. I thought it was an effective thriller. It's mostly confined to the plane but it works. Cillian Murphy makes another great villian as he did in Batman Begins. There's something about him since he looks like a nice guy and all of a sudden he turns into something you wouldn't expect.
One thing I thought would've been interesting is if somehow they were able to advertise it without showing him as the main villian in the movie. The way the movie plays out, you wouldn't have any idea. They set him up as a likeable character and it could lead you to believe he will somehow be trapped in whatever mess the character Lisa (Rachel McAdams) is in. Unlike most movies, it doesn't show that he is in fact a bad guy until he reveals his intention to her on the plane. If we hadny been shown he is the villian, it would have been a very effective surprise. Although since the movie revolves much around him terrorizing her, it would be hard to get the point of the movie across without showing any of those scenes.
I was really impressed by the movie. I was a little worried since some reviews weren't veery favorable. I'd give it an 8/10
