I’m not a fan. “Oh, JK Rowling’s neighbour had a boy who went to a school, that’s where she got Hogwarts from.” If you can actually trace an idea back to a specific source then either bully for you or where’s the lawsuit? I think it diminishes art to disassemble its parts and claim this bit came from here, that bit was stolen from there.
But since I’m not fussed about Star Wars, bring it on.
