I was reading on wikipedia that the actor Joel de la Fuente didn't like his character of Lt Wong in the show. Here's what I got:
A notable criticism from the actor Joel de la Fuente has been quoted in an article by P. G. Min & R. Kim (under the pseudonym "Michael", on p. 744), in which he describes his perception of a possibly stereotypical nature of his character Lt. Paul Wang, for which (referring to the Silicates story arc) he felt "discomfort" for a role that he describes as "a cowardly soldier who betrayed his comrades":
"Whenever I see Asians in military uniform, I cannot help but recall common images of Asians from the Vietnam War and World War II. They were "yellow-bellied cowards" who took the lives of loyal Americans. They were treacherous and crafty, impossible to gauge. Wang could be seen as all of these stereotypes, I thought.
Honestly, I liked the character. I though he had a realistic response to scary situations like doing a HALO jump for the first time and not being a 'superhero' type cookie cut character. As far as being an negative Asian stereotype, I don't know. I'm not Asian myself so I don't see things from the same point of view but I do hate negative stereotypes. What does everyone else think?
