"this is not just for me, this is for every little girl who looks like me." — golden globe and sag award winner for best lead actress, the lengendary history-maker michelle yeoh.
If rumors are true, now my conspiratorial mind gets why hotd writes all women as cheerleader for Rhaenyra:
It's easier to write only one women instead of two or three, it's easier to send only one name for leading actress award, than two or three, so they thought "let's make the story revolve around her and her only, no need to worry about other characters, Rhaenyra will be the only one to compete anyway".
It's easier to win if they "don't split the number of votes". It was done on purpose, even if the performance isn't stellar due to creative choices, fanbase will make sure she wins.
