A club for those of us who know that Gintama isn't; has never been and never will be; the greatest anime of all time or even a candidate for that title.
Come on now, this is supposed to be the best anime ever made? It even admits itself that Naruto and One Piece is better.
The reasons for thinking this show is overrated may vary from member to member. Some might think it's good but far from a masterpiece and some might hate it from the bottom of their hearts. Whoever you are, if you can think of at least 30 titles that are better than Gintama, you're welcome here.
Also, this club only covers the anime. Since the manga don't seem to be equally popular. But you are of course free to bitch about the manga too.
