What movies do you watch that never get old?

I have sat through Terminator, Terminator 2 Terminator 3 (I quite like that one) but after Terminator Salvation it all went downhill for me, but I sat through them because my sons picked them for a Friday movie night.
One Friday after another .. and another .. and ..
Sooner or later a movie franchise is going to go a bit sour.
One film I couldn't get was The Shawshank Redemption. .

Otherwise I love anything with Gene Wilder in especially Stir Crazy.
