I finally watched the final movie, after watching all other films before it back to back. plus, I have seen most of the cartoon the clone wars. the experience of doing it that way, was a great sensory completeness of fully wrapping it all up and appreciating the entire story. I didn't mind the people who came back in the final movie, the reveals of characters and the story line from start to arc to finish. my one complaint was really the way the emperor looked. I mean come on. Who cares that they didn't explain how he was there; we already know that story line; we needed him to look like the emperor to complete the whole reason he was there. The Snoke reveal was hokey I give it that . . . and my partner absolutely hates the actor who play s Kylo Ren. He is convinced the series would be that much better, with someone else in that role. I like him and feel he fits, fine.
A, not plus or minus, just A. Worst of the whole series is Solo, followed by The Clone Wars. Best of the series, is Empire followed by a tie of Return of the Jedi / Rogue One.
