Nominations for the best movie sequel

We have a poll for the worst movie sequel and I'd like to start a poll for the best movie sequel. But first I need a few nominations. In order to qualify the sequel has to be better or as good as the original movie.

The list so far (edited):
Terminator 2
Godfather 2
The Empire Strikes Back
The Return of the Jedi
National Lampoon's Christmas Vacation
National Lampoon's European Vacation
Road Warrior
Evil Dead 2
Bride of Frakenstein
