My like Gurren Lagann, Gintama needs no introduction and it is very hard to explain why I like it. It has action and comedy rolled into one package. It breaks the fourth wall in a way that it makes you laugh every time. It is very hard to tell filler from actual story. All the situations that the main Character Gintoki gets involved in are rather extreme. The cast of characters in the show really complement each and make every thing go together. Just remember that the show does in fact somewhat parody other shows and that the characters know that they are in an anime.
