Just because she saves the books doesn’t mean she’ll be married to the dogmatic views expressed in them. It was Luke that seemed beholden to that narrow minded view of them, not Rey.
It’s not as much a complaint of Rey as a character but rather the fact that the shot of the books is not needed and unnecessarily clouds what was otherwise a simple and powerful message. There’s just quite bluntly no need for the shot of the books.
Hard disagree. It shows one of the means of how she will continue her training. It doesn’t cloud anything. The message Yoda gives is not that the Jedi’s stubborn minded ways needed to end, not at all. The message is that Luke’s stubborn minded ways needed to end. Again, he was the one beholden to them, not Rey. So the fact that she has them in no way means that she’ll agonize over them in the same way Luke did (notice how the shot itself is actually part showing an action Finn does, we don’t see Rey with them at all. The last we see of Rey is her with other people - the suggestion being that she won’t soon end up in the same rut of isolation as Luke).
