Shawshank Redemption and Forest Gump are two movies i can never get tired of watching. As far as comedy anything in the 90's with Jim Carrey, and the Naked Gun movies were great.
I heard the new movie Taken is good. I got Netflix so I've been watching a lot of movies lately... Hotel Rwanda, Flags of Our Fathers, Eagle Eye, Mystic River, Crash, City of God, City of Men, A River Runs Through It. And I always enjoy the Bourne series no matter how many times I've seen them. Oh yeah and The Departed, The Bookdock Saints, Unforgiven, 3:10 to Yuma.
