She makes a lot of assertive statements with no real evidence to back it up. Not sure what to make of it.
"Tolkien wasn't anything special."
"Why hasn't there been another Tolkien??!?!?"
Kind of implies the first statement is false.
I would argue we DID have another Tolkien after Tolkien, he just wasn't writing books. If you want to talk about a fantasy with a massive cultural impact, you don't have to go farther than Star Wars.
