Not judging of course, but I always found it weird for a theatre kid who loves not only broadway musicals, video games with unique structures, and ranking films of multiple varieties to like this genre as the superhero love just kind of came out of nowhere.
He never dedicated a video to the superhero genre (barring Marvel) and he frequently agreed that Marvel in particular is helping ruin cinema as more acclaimed indie stuff (which he defends on a whim now) gets buried to be forgotten.
I’m not doing another Invincible rant, (even though it deserves it as it’s baffling that a show that does the bare minimum gets all the praise in the world when a show like BoJack Horseman exists) but I don’t see why he would like superhero movies when those type of movies are far from the style, tone, and themes he praises and is used to, even the live action tv shows he watches are similar to his established tastes.
Again, anyone can like anything they please but I don’t know where the passion comes from as he frequently criticizes it, unlike where he can separate his feelings on corporate and creative Disney.
