awesome
but yeah, just started watching Paranoia Agent, so far am loving it.
and it too has a great opening
also, for a discussion on sports manga, anybody read Eyesheild 21? right now it's my favorite manga next to 20th Century Boys. it's a shonen style series about a football team and how they rise to become one of Japan's best. The characters are all awesome and the way that they show the game being played is enough that while some parts are exaggerated that a few of the teams are this short of superhuman, it still sticks to the core elements of Football as a sport and doesn't turn into some weird DBZ clone of a sports show.
there's an anime version too, but i highly suggest reading the manga as it has alot more in it and tbh from watching a little of the anime, it's alot funnier and more exciting.
