As such, this trilogy is like that game where you fold a piece of paper and each person takes it in turns to draw a head/torso/legs then unfold the paper and see what weird monster drawing you end up with.

That’s such an accurate description in my view. RJ mostly disregarded every setup of TFA. Take the simple example of Han telling Rey and Finn, that Luke went to look for the first Jedi Temple. Given that setup, and Luke’s emotional response at the end of TFA, you would expect he had gone there in hopes of finding some ancient wisdom to deal with the threat of Snoke and Kylo. The TFA script states:

“Older now, white hair, bearded. He looks at Rey. A kindness in his eyes, but there’s something tortured, too. He doesn’t need to ask her who she is, or what she is doing here. His look says it all.”

So, why did Luke go there? To die. If he wanted to die, and see the Jedi end, why go a place associated with the Jedi in the first place. Seems to me the FO would have found him eventually. Why not go to some random unknown Island? Why not kill yourself, if you’re so convinced it should all end? Why did he wear these elaborate white Jedi robes at the end of TFA? He sure seemed an almost mythical Jedi Master with the wisdom of the ages, waiting for the right person to arrive. That moment and the character of Luke have been completely deflated. It’s twists and shocks for the sake of it, all the while sacrificing the integrity of a classic character to prop up some new ones. Next we’ll learn Han and Leia beat Kylo as a kid. Shocking isn’t it. Bet you didn’t see that one coming.
