A bad but exciting and polarising show gains more popularity than a consistent and good show because there is a lot more to talk about on surface level about the bad polarising show.
Shouwa Genroku Rakugo Shinjuu is the best show since Ping Pong but it's not popular at all. There wasn't much to talk about on the surface level because it was consistent and grounded, but it had a lot of depth, especially in character interactions. An inconsistent and polarising show like Toradora had a lot more going on in surface level and was a much wilder ride than Rakugo, despite being worse.
Go figure why melodrama is popular.
