Gintama... for me it became more than just anime. somehow resembles One Piece.
among all comedy which makes you laugh out loud every time there are awesome characters. can't explain it, but they're somehow like old buddies. after a week you just pick up one more Gintama episode and life become better. all of them act stupid 90% of screen time but it makes them so "alive" and "human", like you meet neighbours or somebody you know for a long time.
*gone for therapeutic dose of Gintama for today
Nothing lasts... but nothing is lost.
