Long Form Youtube Content

I love me some long form youtube content but I have now come across the issue of having seen so much of it that I don't know what to watch next. The only long videos recommended to me now are either true crime (which I am not always in the mood for) or just about topics I have zero interest in. I finished the Quinton Reviews 8 hour Victorious video in a day and now I feel empty because where do you go from there.
