1 and 2 are about even. 3 is a little lower than them, but not by much.

The first two really are parts 1 and 2 of a story. The 3rd completely changes the scenery, which gives some people the impression it’s not as good. It is though , and it ends the story well.

Then there’s the fun fact that parts 2 and 3 were filmed at the same time. So the impression the films give is backwards from how they were made.
