Chirp, you're not the only one who was able to grasp Back To The Future, Part II. I guess i'm one of the elite. :^)
There's so much to love about it. Getting to see what the future might be like is way cool. Just wish they'd spent more time IN the future. If they'd told the story right they could have spent the whole movie on the future.
The alternate 1985 was pretty wild, and it was fun seeing Marty running around shocked by all that was wrong before getting back with Doc, confronting Biff and going back to 1955.
Lots of great stuff in 1955 too. Like two Martys, two Docs, getting to see scenes from the first movie from a different angle, like when George takes out Biff!
I also loved when Marty tries to get the Sports Almanac back from Biff while he's in his car and Marty's on the hoverboard.
