What's your favorite movie?

My husband and I are semi-watching (I am also perusing Craig's list...per usual) a special on the top 100 movies of all time...which is reminding me of some really fantastic movies that I had forgotten about. They named Citizen Kane as the best ever. Never seen it. The Godfather got 2nd.

So, I'm trying to decide which movie is my favorite... here's some of the top-runners...

Singing in the rain
St. Elmo's Fire
You've Got Mail - Mike and I can practically quote the whole movie.
Hitch - totally makes me crack up.
Gone With the Wind
The English Patient
Monty Python's The Holy Grail - another fun one to quote
The Power of One
Schindler's List
The Usual Suspects
Shawshank Redemption

What would you say is the best movie ever made?
