Well, I just saw it. Some things I liked, some were a little Meh. 3.5 out of 5 stars, though. 3 out of 4 on a 4-star scale. It is no masterpiece, and it doesn't have an "epic" feel that the best movies often have, and that Empire had. But it's solid.
I'll echo the problem many others have with Rey. While circumstances are understandable for Kylo to be off his game, there is no reason for Rey to be so proficient with the Force so fast. That is a story flaw IMO. She should not have been able to defeat him. She's a novice. I've been following this discussion since Thursday and now that I've seen the film, it comes out of nowhere. I literally said to myself "Nah. Oh no. What a contrivance." That said...as others have pointed out, the lightsaber use in this movie is pretty awesome...a nice change from the balletic, overly choreographed quality of the Prequels. They were used like swords. I liked that.
I do like her character, though. And I think it's sweet that Finn is so devoted to her.
Speaking of Finn, I mostly liked him. I mostly liked Poe (though the novel has interactions and characterization for both of them that's been cut from the film....same for Leia and a scene with C3PO). Kylo Ren was okay, but he's a pretty weak Big Bad. After killing his father because he's so desperate to go to the Dark Side, I don't want to see a Vader-like redemption for him. They already copied the first movie enough with elements in this one.
We've had 6 movies of mostly the same vision and style/pacing, because of Lucas and/or Lucas' influence. The differences with this one were jarring because of that. It's not exactly a bad thing but the "modern" style took some getting used to. I do think the pacing was a little off, though. The movie was front-loaded. The "meat" of it felt rushed. But then again, you could say the same thing about ANH.
Not having any dialogue from Mark Hamill was lame. And I really want to find out more info about Snoke.
