Pros: This show is too cute. If it spreads, everyone will become MLs. Imagine if Hetalia was done from a pro-PRC perspective with adorable animals
Cons: Early season 2 is problematic, being chauvinistic towards Tanzanian revolutionaries at the beginning, but the show also emphasizes Mao's appreciation of Africa for getting it to the UNSC and the subsequent duty China has to help Africa rise up in return. Also since the show is propaganda for children, it glosses over things where China was clearly on the wrong side of history, like the Sino-Vietnamese war, or Mao supporting Pol Pot. Purely domestic affairs aren't touched on, so the Great Leap Forward and Cultural Revolution aren't referenced (given the international relations focus, I could let those slide)
