I haven't seen it yet. Will do so Tuesday.
I am not expecting it to be as good as Empire Strikes Back; that's a really high bar to hop. Coworkers have said it's (almost) as good as A New Hope, which is good to hear. (It's better than the prequels, which is also good!)
Me: (having seen the last movie the director's done) Please tell me this movie's better than Star Trek: Into Darkness.
Lindsay the Coworker: (immediately) Yes. Much better.
Me: Thank God. Of course, I'm going into it knowing [OH MY GOD WHY DID I SPOIL THIS] so I hope Abrams gets all the hate mail just because of that scene. ^_^
