Doc and Marty are the best time traveling friends ever. Why? Simply this; time can't separate them. I loved, especially in the first movie, how certain Marty was to not let Doc die. They're amazing in any time and situation, so yep, I cried a lot at the end of Back to the Future III. *Back to the Future Series*
