I liked 9. The actions scenes were good. They tried to tie into previous episodes but I think they tried to do too much. I still don't understand why they have to have a bar scene in every damn film with stupid aliens. I thought the character development (main characters) was lacking in the last three episodes. There were too many one off characters too.
Ren was the gayest version of Vader that I could imagine. Villains are supposed to be menacing. He was just irritating. "ohhhh, I don't know if I have the strength". Probably wouldn't bait his own hook when he was a kid. Han ... you had a damn Mil-lineal. Disappointing.
They should have brought back the Jedi spirits of Obie-Wan, Anakin, Leia, Luke, Ren, Jinn and Yoda at the conclusion.
