Gintama has literally every genre in it.
It can be emotional, but stupid
Violent/bloody, but hilarious
Weird, but awesome
I feel like every genre an anime can ever have is packed into this one anime.
Even as a Naruto, Bleach, One Piece, and Fairy Tail lover, I'm willing to say that Gintama is better than all of those animes
Please give it a try if you haven't already
