I think two is actually my favorite Back to the Future movie, which isn't saying much. About a year ago I went back and watched the whole trilogy and was thoroughly disappointed. These were some of my favorite movies when I was younger, and after not watching them in so many years, they came off as really cheesy and over-the-top. But I still felt the second one was a ridiculously fun revisiting of the original, and I really enjoyed the cross over. Three on the other hand, I felt was just silly through and through.

Part one is and always will be the perfect movie. It's my all time favorite movie and I watch it at least once a year. Thoroughly disappointed? The only part of the trilogy that's disappointing to me is the future setting (2015) in part two.
