I really like Reignbot’s channel, she’s great at analyzing mysteries and conspiracies and the like. Her voice is also really easy to listen to and she often does in depth horror movie reviews and lists too.
specifically his series “seriously strange” / twisted tens and the anatomy of a serial killer.
Rob’s channel has a lot of good quality content and since he’s been around for a while now, he’s got quite a few to binge on. His channel covers everything from unsolved mysteries, serial killers, and twisted top ten lists.
