If you are a fan of movies that feature a twist ending, you will love the films of M. Night Shabba Doo. One of his most famous films is the medical thriller Dr. Boogie:
Twist ending: He's not really a doctor!
Here's another M. Night Shabba Doo film with a shocking twist ending:
Who the hell could have seen that coming? Even the cast was surprised!
As an aside, I've never seen The Sixth Sense. I'd read a review of it in the local paper, and shortly afterwards a co-worker had mentioned that she'd seen it, and that it had an incredible twist ending. I was familiar with the premise of the film, so I said, "Incredible twist ending? Let me guess- **REDACTED: SPOILER**." She scratched her head and asked, "You're right, how did you figure that out?"
Sheesh, doesn't everybody have to read Ambrose Bierce in middle school?
As another aside, one of the best movie reviews I ever read was a review of Breakin' 2: Electric Boogaloo which proclaimed that the movie was "primarily of interest to Shabba Doo completists." I wish I remembered who wrote that brilliant line.
