My friend watched Gurren Lagann, after thinking it was just some childish dumb bullshit for so long.
"No, dude, watch it like an action movie. The robots are powered by manliness and screaming." He eventually watched it and loved it, like I knew he would. Point of the story being, we were talking about it, and he goes, "You probably thought the girl with the fang was the hottest, you pedo."
And he's right.
