So many...I'll list the first five that come to mind.
- Star Wars IV
- Star Wars V
- Star Wars VI
- Office Space
I'm not much for reading a book more than once, but I have read Jurassic Park about 10 times. Crichton's best, IMO.
Generally, I like to watch/read something new. I'm the same with traveling; even if I really like a place, I won't come back because there are so many other places to visit.
