TCM is terrific. No commercial interruptions and a great place to find noir films, which are my favorites. I believe I've watched DOUBLE INDEMNITY over a dozen times. It never gets old.
Speaking of the late, great Spencer Tracy, I thought he was also excellent in the film BAD DAY AT BLACK ROCK. Including a top-notch supporting cast of Robert Ryan(one of my all-time favorite actors), Lee Marvin and Ernest Borgnine. That's another one I've watched more than a few times.
