I wish none, because I find YouTube's algorithm thinks I want to listen to the most melodramatic and cynically pessimistic TV and film reviews I've ever heard, along with politics in a similar vein. And worst of all are these crappy video essay channels that say a lot of irrelevant stuff around a point.
P.S. to answer the question, I'm subscribed to about 382 channels specialized on video essays about political activism and film criticism.
Also, fail army.
I describe myself as a little dose of toxic masculinity.
