This film is my least favorite of the Trilogy. For some reason the alternate 1985 never really worked for me, and prevented me from really getting into it. I did enjoy the "Future" which is now less than seven years away, largely because I enjoy seeing how various time periods envision the future.
The second and third movie were written and filmed at the same time, so throughout the second movie we see foreshadowing of the third movie. I do appreciate a film that takes the time to work out these sort of details, and I think it leads to a more pleasurable movie-viewing experience. Unfortunately beyond the last scene of the first movie, I don't know that the second and third movie were planned, which would have really helped to tie the entire series together even more than it already is.
Marty: No, I know; you did send me back to the future. But I'm back. I'm back from the future.
Doc: Great Scott! [Feints]
