I'm no fan of anime. but I only watch attack on Titan and OPM
aot will get you hooked with it's mystery, conspiracy and throws camaraderie out the window unlike those power of friendship bullshit on most anime.
OPM is making fun of all anime.
I urge you to watch aot bro it's great. BUT right now it's plagued with batman mantra. that nonsense "if you kill your enemy youre no better" bulshit
