I never write reviews for shows. But after binge watching 353 episodes in a span of 3 weeks, I have to say Gintama takes the gold and the silver, balls and all.
Gintama has both wonderful gag arcs and dramatic arcs, with compelling characters to boot. The comedy in Gintama is HILARIOUS, with all kinds of clever, random, witty, and, of course, dirty jokes. The fourth wall is practically thin air
