I used to eat dumb fun action shows, but after I suffered a year of bullying because I wasn't a hood nigga, or get harassed by the wonderful West Virginian racism, I fell into a deep cycle of depression, where anything that resembled happiness I rejected. I needed bleakness, because that's the only thing that comforted me. Let me know that I wasn't alone.
As I grew up, my depression faded, but my cynicism still remains. That's not fading anytime soon. At least I know that I can give the shows a chance.
I feel that, I found out that I was much the same when I finally realized I was going through depression (instead of thinking it was a phase or just who I turned into). I suddenly only wanted to watch the dark and bleak dramas, couldn't stay interested in comedies or light hearted shows unless I already had a nostalgic connection(old shonens).
Now that I beat the depression, I still can't watch comedies because I just lose interest, I just get bored. I need serious story-driven media, with hardcore drama and grounded worlds. No plot hax or unbelievable power ups, just characters using their wits and strengths to survive and get on with their dire storylines.
Which is why I can't get interested in things like Gurren or KLK, gimme dat Monster
( I still need to watch Monster, though I've read a good bit of the manga.)
I get all of my comedy kicks out of watching TBF or RedLetterMedia though.
