Back to the Future III

As far as I know, this series started the phenomena of making a group of movies and releasing them over a period of time. Someone needs to be beaten to death for that. I caught part of this movie the other day and still thought the story about a teen and his mad scientist friend who are attempting to return to their present after being stuck in the past due to the invention of a time machine was as cute as when I first saw it (as was the original, but the second one was garbage).
