I only count axed and short ones because the ones that go on for a long time and finish properly will eventually run into the issue that the eternal underdog MC will have to face a "talented" villain that is for once also a hard-worker (because surveys showed that even rabid fans are no longer buying that every villain is simply conveniently lazy and arrogant), so the MC can no longer make it about hard-work vs talent and has to compensate by finally activating his dormant secret ancient bloodline he had all along, which can be considered a cheat.
