I too think Monster sucked. I have no idea why /a/ has such boner for it.
Psychological anime? The bad dude made people kill each other by saying "lol, your wife cheats on you and you suck".
Also Kenzo spent fucking long time tracking Johan, learning how to kill and witnessing how he killed shitload of people with his miracle powers and then when he points a gun at him.. BAWWWWW I can't do eet BAWWWWWWW. Same happens again: BAWWWWW I can't do eet BAWWWWWWW. Shit starts to repeat.
They should have squeezed this anime into 12-24 episodes or to save some of my loath just give Johan some sort of "real" demonic powers which were given to him by nazi experiments instead of trying to explain everything by HE SO CLEVA.
