I watched some transparent and got fairly annoyed. I didnt originally have issue with the idea, but on some level it seems more like blackface. Almost a mockery rather than portrayal. I think it has become important that we take the roles, to sidestep the stereotypes involved. I admit a transgender character can certainly be well done even by a cisgendered actor. However on some level it simply brings an air of "nothing about us, without us".
I am clearly biased, but I would also argue that there should be more non binary individuals as well.
Edited: To better explain myself. I do not believe it is necessarily bad for the role, just lack of representation
