Not me. 2 is my favorite. 3 is a western, so that alone puts it at the bottom (although it DOES have some good stuff in it, the non-western parts, for example.) And yes, 1 is good, but not as good as 2.
I'm not a big western fan either, I just thought the third movie had a lot more heart and charm and humor than the second one.
The only thing I wish is that they somehow worked the Delorean into the story more. My favorite scene in the trilogy is the Delorean being chased through the desert by the indians-- just for the crazy imagery of a 1980s sports car, on big 1950s tires, in the Wild West-- and I would have loved to have seen them have a lot more fun with that idea.
