I've spent the latter half of 2020 watching through the series to figure out what the fuzz was all about. Ninjago's just another one of those action shows with color-coded heroes and way too much inconsistent lore. Still, the cartoon is one of its main selling points and fans went rabid every time the series seemed to end on a season. I don't think it had any real competition during its running time either, so I can figure it quickly became people's favorite childhood memory.
Of course, season 14 is already available online and season 15 comes right after. I don't know why the hell this show keeps going, I actually resent it a little for eating up every other IP LEGO could've had. The lore gets changed every damned time just to fit the crappy writing, and I wish Jay would die for drama already. No character is as unfunny as him, it's even acknowledged in the show itself that a lot of people just generally hate him.
