Having watched it, Ray is about the only thing seriously dragging the movie down for me.

Everyone immediately loves her, she instantly excels at any task put in front of her regardless of how believable it is (Everything she did on the Falcon, immediately learning how to both defend her mind AND in turn read the mind of Kylo Ren, having never even seen it done before she was able to pull off a Jedi Mind trick on the storm trooper, both of these done without any kind of training, and after Kylo Ren is clearly beating her in their duel she's all 'hey I can just use the force' and proceeds to immediately kick his ass badly. I know he'd already been shot by Chewie and cut by Finn, but that fight was still so one sided up until 'lol force' that it still felt ridiculous.) And among all these things, there seems to be no flaws. You get one brief moment where she has a hard time accepting her past after grabbing the light saber, but that's pretty much it, and it's not really a flaw its an entirely believable reaction to what happens, yet is never touched on again.) The actress was great, but the character itself was just terribly boring.

Outside of that and a couple minor issues here and their, I thought it was pretty great. Casting was excellent, I loved Han and Chewy's comeback (Even Laia was pretty awesome), the call backs were amazing (I laughed so damn hard at the Trash Compactor line), Finn and Co (The Pilot Finn escaped with) were both fantastic, the action was great, and so long as they don't mess it up I think Kylo Ren has a lot of potential in this story.

And I had the Han thing spoiled for me before hand, but it still hit me hard when it happened.
