I'd forgotten West Side Story - just got it on DVD - the ending makes me cry everytime.

The one I will watch again, when I'm in the right mood, is Schindler's List. My Ex wasn't one to sit through anything too long so I didn't tell him it was about three hours and mostly black and white. He came out of the cinema totally blown away by the film and I had to give him a potted history of the Holocaust as he really (even at the age of fifty) hadn't paid any attention to what happened there. Terrific film, but not one to watch when stressed or depressed!
