Agreed, 1,3,2. Although you couldn't have 1 and 3 with out 2, 1 & 3 were the best. Personally I would have been happy with 1 having a slightly different ending where the Doc destroyed the time machine but hey can't complain to much.
I wish they had left out Doc's obsession with destroying the time machine, or at the very least made it make sense. I remember him taking about destroying it as early as the beginning of the second film, and as a kid I was like, "whaaaaat?"
I mean, sure it is dangerous to travel through time. But doesn't that indicate the need for increased security (i.e., not allowing anybody who wants to drive off in the time machine). Didn't he wrestle through these pesky ethical questions during the 30 years between thinking up the time machine and actually building it???
To me, it was nothing more than an excuse to end the film series that smacked of lazy writing. To make matters worse, they then have Doc Brown turn around and invent
another time machine! Character consistency be damned!
