It wasn't easy to find a good ending to the saga: Ep. VII and ep. VIII were so different... Ep. VII was a traditional SW movie, almost a rebbot of ep. IV, while ep. VIII tried to change the "tradition" doing something original (why?!? SW is something like a religion! You can't change it's canons). TROS does its hard job taking back the saga on the old way, at cost of some unavoidable loss of coerence. I think JJ couldn't do better than this...
