Films where the 3rd one is the best in the Series

OK, here's a challenge for any readers... Which film series were produced where the 3rd film was the best?

I think Indiana Jones and the Last Crusade may be the best 3rd film in a series, but I still think that Raiders of the Lost Ark tips it. I also quite like Return of the Jedi, but it ain't as good as the 1st two.

The only one that I think might deserve it is Return of the King, which was grander than the originals.

Any thoughts?
