I've always been apprehensive at the prospect of a Shang Chi movie because of this. I don't think they should touch the Fu Manchu stuff at all and just give him a different origin. As much as people complain about characters getting changed when it involves changing their race, no one ends up giving a shit if a character has a different origin story. Personally, I find Iron Fist's origin and mythology a lot more compelling, and I wouldn't be surprised if they steal a bit from that.
I just want to say, that I have an ex who, my opinion, was a horrible person. She had a tattoo that read "danse macbre."
You username brings me much joy.
