The first 3 are pure gold, the next 2 are decent, from Jotaro's daughter onwards the saga died

Digimon is another case. After Tamers ended, its audience fell, there was a nostalgic comeback for the sequel and a remake of Adventures, but they were ultimately poorly received.

Yugi Oh could never match the success of the first series, and BeyBlade was forgotten in the West after the third series.

Apparently, the magic number is 3. It's not a rule, but it's the longest a big fandom can handle with different protagonists, after that it fragments and becomes a niche thing.

I wonder what would happen if the One Piece story took place over generations and the protagonist had been changed 5 or more times.
