The main story arc was stupid and terrible.. and resulted in the slowest chase in movie history because they were low on gas!?
The secondary plotline was completely irrelevant to everything and everyone. Hating on rich people at a casino and then beating people over the head with heavy handed and incredibly simplistic morality before riding a pack of animals around and trashing the place!?
Most of the characters are two-dimensional and had no development whatsoever.
Annnnd they wasted Luke Skywalker's last appearance. After doing a very poor job of the build up throughout the (overly long) bloated mess of a movie, they wasted their last chance to redeem it with Luke going out like the legend he was despite his protestations.. and instead did a stupid gimmick for the final confrontation so it ended up having no emotional resonance at all.
Like it was bad, man. Just all around terrible storytelling.
But hey, it's making a ton of money so prepare for more of the same.
