I mean, that's a pretty old troupe seen across mythology and folklore so I'm perfectly willing to give it a free pass. Star Wars' bread and butter is in taking those core myths and putting them in space.
That said, setting aside the crap execution and crap ideas found elsewhere in TLJ, I do like the idea that Ben turned to the dark side because he couldn't handle the weight of the family legacy. He fears that he'll never live up to expectations, that he's not strong enough to carry the Skywalker name, that makes him turn to other sources of power. And in the end, Luke couldn't handle that family legacy either, and was all too quick to believe that another Skywalker had been corrupted.
We've seen rage drive people to the dark side. We've seen fear do it. Even love, after a fashion. But Ben, I think, was the first time I've seen someone fall due to simple insecurity.
There's a lot of interesting stuff in there.
Actually, if I remember right, the Knights of Ren were already a thing in the academy when Ben and Luke fought. Has anything covered this? How did a group of students start following the dark side without Luke noticing?
