Gintama is the alpha and omega of anime. The only anime on the planet that can induce every single emotion that can be felt by a human and does it in 20 minutes. They also troll the shit out of everyone, anime and the real world, to the point that one time they had an entire episode where they did nothing but apologize for the shit they did up until that point ... apologize by saying they're sorry for doing it ... while showing you again lol. It's like "hey we're sorry we did this .... but we're gonna do it again real quick ... ALL of it.."

Gintama is worth watching if youve seen lots of other animes. Its a comical series that takes the piss on a lot of other animes/mangas and typical japenese culture we probably dont even understand. Its a very long running series, and can get dull at times (stupid fillers). But a must see for the true anime fan (just to see if you get all the references they make)
