Watching the "Back to the Future" trilogy is like crossing an old, rickety bridge. It starts off smooth, gets rough in the middle, and you start getting your hope in the rough part and cross the bridge saftely. Okay, this probably isn't the best simile I can come up with but this is how I would put the events in the trilogy. If you've seen this one, you probably understood the simile.
Part 2 follows Doc Brown and Marty McFly as they travel to the year 2015, thirty years after the events in the first film. They must prevent Marty's future son from going to jail. While that happens, the future Biff Tannen gets ahold of the DeLorean and goes back to 1955, changes the events in the first film, and creates an alternate, dystopian, 1985. What do Doc and Marty got to do? Go back to 1955 and fix up the screw-ups Biff made.
This is my type of movie. As much as I liked the first entry, I thought this was a bit better. RT's Tomatometer disagrees with me on that. This is the intense, nail-biting sequel. A very worthy sequel as well. The rough part of crossing the bridge represent the intense events in the film. Bet ya didn't know that Zemeckis and Gale did not want to make a sequel but were forced by Universal Studios to do so. They did it very well. Everything was great about this sequel except the abscense of Crispin Glover. Not even the archive footage can make up for his loss.
Definetley a better sequel. Great film with an excellent structure.
