- Looked great. Like, really great.
- Too many characters with too little to do
- Does not fit into a supposed trilogy, at all:
* The themes of the movie (anyone can be a hero, we must learn from our failures) are worth exploring, but would have better suited Rian Johnson's stand-alone project. Here, they come at the price of throwing over the movie's shoulder every thread left from TFA (quality of said threads being another matter...).
* Getting away from the hamster wheel of dark lords getting redeemed or laser-stabbed by fiesty youngsters is likewise a good idea, otherwise each movie is going to be like images in facing mirrors, repeating endlessly. Again though, this is a sudden 90 degree turn from the trajectory of the first movie.
* Twists aren't bad, but require build up or foreshadowing, otherwise its just the writer telling the audience "Ha ha, I tricked you idiots!"
