There aren't a lot of ninja around anymore. Not just the shinobi in the fiction of the series, just ninja media in general.
I feel like the last big one was maybe Naruto?
This came out of nowhere and delivered some solid ninja stuff.
It's also funny, which is a bonus!
That said, the pacing was a bit too slow at times, felt like it could've been edited tighter.
And while I kind of get the Britpop music choice, it really didn't work with the show for me.
I do hope they make another season, though I'm not expecting it, considering it's Netflix.
