The movie at most makes you Think about the implications of Star Wars’s most basic themes (war is bad!!) but at the end states that “getting hope and learning from the past is good and fine actually.” The closest it actually gets to criticizing star wars itself is the note about bloodlines not being the most important thing in the universe.
The movie pretty clearly conveys the message that the past has little to teach us and we need to look inward to ourselves to move forward. The message is somewhat muddled, but it’s in there. And I’m not talking about Kylo Ren’s famous line “let the past die, etc.”. I’m talking about the fact that Rey learns almost nothing from Luke, and then Yoda belittles the “ancient Jedi texts” before burning down the Jedi library while laughing about it, and saying Rey has all she needs by herself.
This message utterly sucks. The message is somewhat mitigated by the fact that Rey brings one of those “ancient Jedi texts” along with her to learn by herself. But this doesn’t really change the overall message much. Why does Rey need to learn by herself with a book when she had access to a real-life Jedi Master?
