I'll let you in on a little secret, it is exactly how it is "...And then This happens..." is a JJ Abrams staple. However, the issue is that if you use those powers as per the Disney Trilogy, you've just opened up the door to a whole slew of abilities that the Force can do. In fact, there's nothing it can't do at that point.I mean, I think that requires an after-the-fact rationalization, I don't think there was any intended continuity going on. The sequels reminded me of the scene at the end of Superman II, where he just starts pulling new powers out of his butt because...reasons (cellophane expanding S-symbol, multiplication, teleportation). It all came across as very "and then this happens" style of writing.
