These five are all great. The two I would rewatch most readily are Psycho and Dr. Strangelove.
Wow, I've actually seen 4 out of these 5! "Dr. Strangelove" is definitely a must.
Yeah, it's probably pretty wrong that I haven't seen them. If I ever get enough time...hah, wouldn't that be nice. Christmas break, maybe? Oh, the joys of college.
