I've not mentioned any spoilers, though just in case I tell one.... So anyway, Gintama is a fantastic anime to watch, it's overall very nice and interesting. There's no main character, but each and every character combined makes a single main character. Not only that, but there's a a huge variety of jokes - Situational jokes (the funniest ones), Sexual adult jokes, poop jokes, fart jokes, vomit jokes, word plays, parodies of other animes and what not, the list keeps on going. Not only that, there's also a lot of badass serious arcs with badass fights, emotional moments, painful deaths and epic conclusions to these arcs.
All these things makes it a perfect Action-Comedy anime.
