It was fine. My biggest problem with it is the retcon. Apparently, modern star wars wants us to pretend Jedi didn't happen.
I'm not sure what you mean by this. Episode 6 happened and it has not been retconned at all.
I don't understand why people take issue with the First Order. If people complain about that than they should complain about Empire Strikes Back.
They blew up the Death Star and beat Darth Vader in A New Hope. Empire destroyed.
Aahh no son, still heaps of the Empire left and they gonna kill the rebels on Hoth.
The Empire controlled thousands of planets, why would you think they were defeated after destroying 2 Death Stars and killing Palpatine? There are probably 100 other people under Palpatine who believe what he believes and under each of them thousands of soldiers.
I'd love a movie set between ep 6 and 7 because that's most likely where you'll get some incredible full scale battles. The battle of Endor was just the start, it showed the Galaxy that they can fight back.
