Touchy subject. I too thought "2001" was overated when I saw it as a kid. As an adult I had an entirely different take.

"Titanic" - Overated as hell "wha' the ship's sinking?"

"The Deer Hunter" - Wha? Viet Nam was bad?

"The Dark Knight Rises" - Batman quit for 10 years? Batman NEVER quits!

I could go on and on and on...
