Personally I really didn't enjoy this movie and here's why (WARNING THIS MAY BE VIEWED AS OFFENSIVE TO OTHERS AND THERE IS SPOILERS):
1) everything was just to predicable, I mean this in that you know what will happen 10 minutes before it even happened
2) Reys powers didn't make any sense, somehow this chick gained MASTER level force abilities from god knows where defiantly not from Lea as according to the movie she stopped her training before she could be recognized as a actual Jedi
3) there is legitimately no expanded proof of Palpatine having a wife let alone a daughter so it makes no sense that somehow Rey is palpatines granddaughter!
4) it seemed to me that Disney is trying to please the SJW and feminist by giving them a female character who is apparently the strongest Jedi ever
