The Prequels are a good story told poorly. The Sequels are a bad story told well. I like 'em both in their own ways. They each have a really bad episode in them (AotC and TRoS) with two more that are pretty fun.

Why did Luke blame himself and walk away from everything, as Han said?
Why didn’t Luke sense Han’s incoming death and come to his aid?
Is Finn force-sensitive too, and if so, will that get in the way of Rey being the supposed new Jedi messiah?
Is Finn the “backup messiah”? Or is that Kylo, since he will obviously be redeemed?
Is Finn gonna be the new face of the rebels, while Rey is the new face of the Jedi, or is that Poe, since the script decided to leave him alive at the last minute?

Those aren’t mystery boxes, they’re just speculation. Plot holes if you really wanna insist they’re essential. The movie never asks the audience these questions.

Rise of Skywalker is a blast to watch because it’s so ridiculous and insane

I actually agree with this. This has been my stance on the movie since it came out.
