The voice actor specifically addresses some of the problems, and how he wanted to avoid stereotyping and caricaturing in his performance:
Hardly absolves some of the writing/direction choices or resolves the criticisms, but it's worth a listen to for some context from his perspective as a PoC.
I empathize with the difficulties he faced in wanting to portray a much broader character than the original while still being relatively faithful, and it sounds like he had more agency in some performance choices than simply acquiescing to direction.
I wonder how he views the train scene after seeing it.
