They are resisting the first order. In return of the jedi all they did was destroy the 2nd death star. There is still a huge fleet of star destroyers and a large ground army.
My problems with the plot are 1. this new super death star was only protected by about 30 tie fighters. 2. The sith lord kylor Ren seemed to be an even match for 2 different people who have never even picked up a light saber before. 3. I dont think that storm trooper captain would have turned the shields off at gun point because of how they are trained and conditioned. Seems like she didnt really put a up a fight, and wasnt willing to die for the cause.
Overall though i would say it was good not great.
