I don’t really see how TLJ contradicts esb.
Well I would say Rey’s almost instant mastery of the Force contradicts TESB. The entire premise of TESB’s plot involving Luke is about Luke training to become a Jedi, and everything that goes with it. Luke ignores his teachers advice, and he pays a hefty price. Luke’s struggles in controlling this mystical energy field is in stark contrast with the ease with which Rey is able to just do anything she puts her mind to, whether it is beating a host of Snoke’s elite guard after she’s only first laid her hands on a lightsaber a few days earlier, or lifting a ton of rocks to save her friends. Then there’s this concept of the Force balancing the rising darkness with creating some light side warrior, or perhaps even warriors considering the broom boy at the end of the film. That seems more consistent with PT canon, and the whole prophesy of the chosen one, but even Anakin had to go to Jedi school for about a decade to learn how to control the Force. I have less of a problem with these things now than I did before, but some of these concepts could have been better developed, such that they less contradicted much of the information we recieved about the ways of the Force in previous films.
