I was really shocked by what happened when Marty took out a weapon; it had me laughing.

It’s okay, I guess (seriously, what was the point?).

This third installment didn't quite live up to expectations; I watched it ahead of time with some colleagues. While it’s better than the first two movies, it just didn't work out well for several reasons. The conclusion especially seemed contrived and very strange. It wasn’t a satisfying way to finish things off.
