I think that's just modern films for you. I did miss the old style pacing and felt that the finale felt underwhelming because of how short and easy the mission felt.
Though it's also the problem with having the two main characters to establish, follow and build rather than just Luke. Things just take more time.
However I expect Rey having a mysterious past/training is going to a subject for the later films, in which case having an extra hour (a really, really long time for a film, incidentally) isn't going to solve much.
