My favorite part of these films is how well it incorporates the fantastical with our mundane, hyper technological contemporary society.
Maybe I'm reading too much into this but it feels like a metaphor for geopolitical tension and arguments for peaceful co-existence and mutual cooperation between China and the west.
Some amazing comedic timing, especially the dynamics between Nezha and Wuxian or Lu Ye filming Xiao Hei's fight with the fake Wuxian.
