Weekend Rock Question: What Is The Greatest Movie Sequel Of All Time?

It seems like Hollywood churns out more and more sequels every year. Some of them, like Anchorman 2: The Legend Continues, are pretty great.

We remain cautiously optimistic about Dumb and Dumber To, though sequels that come out decades after the original are rarely great.

Now we have a question for you: What is the greatest movie sequel of all time? Feel free to vote for a classic like The Godfather Part II or The Empire Strikes Back, a overlooked comedy gem like Addam’s Family Values or Bill and Ted’s Bogus Journey or something campy like Rocky IV. Vote for whatever movie you want, but please only vote once and only for a single selection.
