Hmm, this is tricky since I'm not sure about your movie preferences. I just saw Friday Night Lights and it was fabulous. If you're a football lover, I say add it to the queue. Another of my all time faves happens to be another sports movie (specifically, baseball): Cobb with Tommy Lee Jones. It's great -- funny, sad, inspiring, you name it. Okay, finally, if you haven't seen the Shawshank Redemption, it's a must see. It's almost hard to believe it's a Stephen King story -- not scary (as is his usual fare) but a tremendous story of the human spirit.
Netflix rocks...you'll love it.
