I did kind of chuckle at how immediately Luke went off and changed his clothes after meeting Rey (I guess Johnson didn't much care for THAT outfit, lol) but I got the impression that Johnson made the film that most struck his creative nerves and then tried to reverse engineer it to fit with TFA. A lot of people are acting like he totally erased everything built by TFA "Alien 3 style" but that just isn't the case. It continued TFA, while continuing a character we hadn't seen since ROTJ, while also paying some lip service to how current events evolved from even the PT. I saw a lot of respect being paid to previous films while still allowing fans to pick and choose which ways they want to "fill in the blanks."
