I recently started watching this guy, Philip Chase, a fantasy book reviewer that started about four months ago. He's really good. I think he's an English professor. He does a really good job at reviewing books and series very thoroughly. I highly recommend him if you're at all interested in fantasy books, or even in how plots and characterization are structured, etc., as he talks quite about about that. I'm not sure if he's officially a "booktuber".
