He comes across as someone that got a chip on his shoulder that his career didn't take off faster than it did. Yet didn't struggle or take long enough to take off for him to get some perspective and be humble.
Just a slow rise to finally getting on a well-liked, well-regarded TV show. One that probably had a really large global audience, yet never became regarded as a big show.
He finally gets cast in a big movie, and all his ego goes rushing to his head. Yet he has that chip on this shoulder that it didn't come sooner. Has latched onto the current discourse on rate and woke shit. He was entitled to it, but it was because he's Chinese which is why it didn't happen sooner.
Ad to that the fact his film came out during a pandemic, having a lower box office take than it otherwise would have. So everything is bruising his ego. He's gotten to where he wanted to be, but it's not enough and he's pissed off.
