This movie has the worst plot of all the saga, a lot of WTF moments, and corrupts one of the best characters of the star wars universe. In regards to the plot, the rebels are being chased by the first order's destroyers at light speed, so Admiral Holdo, the lady with pink hair (they don't even care to give her a proper background) is the highest rank on duty (at the time, Price Leia is in the infirmary). She has a plan but tells none. That makes the rest of the crew think she will destroy everything the rebellion worked for, sosome of them go rogue. The conflict the film is based on a communication problem...
Like i said, theres A LOT of absurd scenes that will most certainly make you facepalm, like the moment when the spaceship's bridge of the rebels is blown to pieces you see Leia dead floating in space, when she suddenly starts flying back to the ship; or when Snoke, the most powerful man in the First Order gets killed by Ren's dumb trick...
Finally, in my opinion, this chapter corrupted (and even destroyed) Luke's character. Once a legend, he is portaited as a coward that even tried to kill his own nephew. The film tries to redeem him at the end, but it doesn't quite do it. If you expect a fan service fiIm, you will be satified, since there's a ton of references, but if you expect something more, i suggest you save your money.
