Yeah I actually really enjoyed one-man punch. But reason why I think its so good is because its the opposite to most anime, the whole thing is almost just an elaborate parody taking the piss out of how stupid anime is. So i'm basically surprised that it is high ranked on my anime list or as popular as it is among anime fans.
I'm watching full metal alch at the moment, its actually not bad if I ignore how little sense any of it makes. Some of the sense of humour isn't even that bad, and typically always thought anime humour was atrocious and japanese people must just have a bad sense of humour. But have you guys seen Plastic Nee-san? this one is pretty funny:
also have you guys seen panty and stocking? also pretty funny plus panty waifu #1
