Gintama problems :
-Got the Papyrus syndrom "Too fancy and too accessible at the same time" meaning no one will play contrarian with that one and at the same time Casual will prefer something more common -Misconception about The comedy tag : Saying Gintama is an comedy Anime is like saying Monogatari is an harem Anime (ppl might think of Gintama similar as Konosuba/Saiki)
-Weird quality-spike it's meh before Benizakura and it's meh after 2017
All of this add up to make Gintama look like another overrated Top Anime MAL, so circlejerker who are not ballsy enough to just give it a try will just miss it
