None of them flopped except for arguably Kaiju No. 8. The "new generation" of manga artists just aren't in the mood for running their series for more than a decade unlike the generation from the 80s and 90s. They get their 20 - 30 volumes, sell millions of volumes, and then end.
I'd much rather them end than seeing seasonal rot kick in like what happened to all the Big 3, and arguably Dragon Ball with everything post-Z being shit (with the exception of the Tournament of Power). Series aren't meant to go on forever unless they're like JJBA where every part is its own self-contained story within the wider series.
