Ah, this whole trilogy, man.
This is the one trilogy, to me, that actually got BETTER with every film. Yeah, they're pretty straightforward with no twists or plot complications, but that doesn't matter. What does matter is that these movies and everything in them just feels right. Characters, scenarios, humor, morals, the endings.
Especially the ending to this one. Not just the best way to end this movie, but to cap off the entire trilogy. There is ZERO need for a fourth one. Everything feels complete, everybody's gonna be on their own way elsewhere, nothing else needs to be done to enhance it. It's...just right.
