Finally saw the movie, I cried like a bitch when Solo died even though I knew it was coming. My favorite character was Poe, Finn is cool I like the humorous scenes with him. Rey is bit of a Mary Sue but if they expand on her abandonment problems I think she will grow as a character.
In this movie, they established the conflict and solved it within the first movie of a planned trilogy.
The Republic is crippled or destroyed, the First Order is the largest power in the galaxy, none of the villains died, Han Solo must be avenged, Rey must find out her true past and parentage, they still have to explain how they found the lightsaber. The original movie was wrapped up better than this.
Also I wanted to see more of Hosnian Prime before they blew it up, I wanted some scenes of the Republic senate. Can't believe I'm saying this but I wanted more of the Republic politics, George Lucas was right all along.
EDIT: Stormtroopers are actually badass in this movie. Except Phasma.
