What niche YouTube rabbit hole do you recommend?

This is going to be not the technology nor technical ones at all. Once upon a time, I was intrigued by the fact that power-saving economy mode dish washing takes a lot more time while consuming less electricity. While reading up and watching videos, I stumbled on the Boulevard Home[1] Channel and I subscribed.

Otherwise, I have a very limited set of channels[2] that I like to keep going and get lost watching them.

Right now I've been watching this 12 hour analysis of Star Wars Episode I: The Phantom Menace [1] , I'm not a huge Star Wars fan in fact I haven't seen them pretty much since I was a kid, however this video is so entertaining and goes so much in depth over interesting stuff that not only I'm close to finishing it but also I'm compelled to watch all the films now.
