Are we sure it was Coruscant that was destroyed? I mean yeah it looked exactly like it, but why it was never mentioned by name? I think STD might be right
I could see Han Solo's death coming, but I was still shocked and saddened. Kylo Ren interests me . Not being a an unstoppable killing machine probably makes him more interesting.
I think Rey being Luke's daughter is too obvious. I don't know who else could be her parents though. Luke better be one bad motherfucker when he does come back.
