Qui Gon actually did come back, but not a force ghost. He appeared to Obi Wan in the Clone Wars series. I think Yoda talked about this at the end of RotS. So he passed on the training to Yoda and Obi Wan. Vader I guess figured it out on his own?
Did anyone else think Leia flying through space was dumb? That whole scene was very silly to me as she flew through the air like Mary Poppins.
The fuel plot and shields reminded me of Star Trek. I was waiting for Worf to call out "Shields at 40% Captain!"
The lightsaber throw was hilarious. I also liked him wiping the dirt off his shoulder before his battle with Kylo Ren.
Maz said that would be a story for another day in the last movie. Maybe they'll come out with Star Wars: Maz Kanata at some point.
Kylo said Rey's parents were junkers and nobody important. Any reason to believe he was lying? I thought she was going to be related to Luke in some way, but I guess not.
I thought the little kid at the end was going to do some kind of force lift on the rocks around him.
Overall, I really liked the movie. My second viewing will be in imax next week.
