I just watched the finale of series 2 and I have never cried so much. I don't normally write reviews but this show deserves it. There's NOTHING I can compare it to. It's such a unique show. It really feels like a love letter to both animated shows and musical theatre of the last few decades. A show like this only comes around once a decade and I highly recommend it.
After watching Series 2, I fully feel safe in saying this is on par with Avatar: The Last Airbender and I will be adding it to my yearly rewatch list.
