I think it was funny how Lawrence Kasdan in the "Empire of Dreams" documentary mentioned how happy he was that ESB wasn't going to be a rehash of ANH.
I guess rehashing ANH for TFA was what Kasdan needed to do before Lucasfilm would agree to give him the Han Solo prequel film?
The new actors in TFA were good, shame they had nothing interesting to do.
I guess it was more that JJ is too much of a Star Wars Fan and partially blinded to reality.
I said this in my review here after i saw the movie.. it was like he had a checklist of favorite scenes/moments/character traits he wanted to have in his movie and didn't much care if it made sense or was needed in the movie (such as the alien bar scene at Maz Kanata's vs the Mos Eisley Cantina or the Superweapon concept in general).
I hope he cuts the ties a bit better now that he's got it out of his system and gives us an original story for Star Wars 8.
As far as I knw Rian Johnson is the writer and director of Ep. VIII, Kasdan is writing the young Han Solo movie.
