The way they forced the Millenium Falcon in was lame, but guess what? If the ship wasn't in the show, everyone would be asking where it was and what happened to it.
I didn't have a problem with Rey beating Kylo. Kylo was shot in the chest my Chewie just before. Plus based on the new trailer it is obvious she's supposed to be really powerful.
Plus I always got the feeling that Kylo Ren was not supposed to necessarily be super powerful. He seems more like a Vader wannabe for lack of a better term.
Not only was he shot by chewie's really strong weapon and was bleeding out but he also took a glancing blow from the light saber while fighting Fin. At first I'll admit it pissed me off a bit too, there are other things that bothered me in the movie more though like Rey saying "let go of my hand" and her having to help Fin up later, it just seemed to push the feminist message a bit hard for my taste but now I just overlook it, they were trying to make her look strong not make him look weak and while I think they were a bit too on the nose with it it's not like it ruined the movie.
