It was better the second time. First time was catching up on 10 years of waiting, and felt like drinking out of a fire hydrant - so much coming at you that you could only take in so much and missed a lot. Second time I caught a lot more info and able to figure a few things out. Would love to have a DVD and play frame by frame the vision by Rey - happened so fast and so much intel from that brief part of the movie.
Something tells me that in the end all of the Skywalkers will be on the same side fighting evil. People say Kylo is too far gone, but Anakin wiped out all of the younglings in Revenge of the Sith, helped axe Mace Windu, tried to kill Obi Wan in 3 and did so in 4. The whole saga is a huge allegory showing how good and evil exist in everyone, and that there is always a battle between the two. It also shows no matter how far you have gone to the wrong side you can always come back and be forgiven.
