Pegg’s got a great response to Takei: http://www.ew.com/article/2016/07/08/star-trek-beyond-simon-pegg-sulu-george-takei
I dunno. Seems to me a little like changing Bruce Banner to an Italian American as a nod to Ferrigno. Something that’s pre-established in reality.
OTOH, I suspect that most if not all homosexuals have an imaginary straight alter-ego, a sort of “What if I’d gone in the other direction?” Sounds like Takei might have played his Sulu that way and was a little thrown by another take.
Not being immersed in the TOS EU lore or Takei’s personal characterization, I don’t feel bothered by a secondary character having his character expanded with an acknowledgement of the original actor. At least, so long as it is a simple acknowledgement and not a glorification or press to normalize the unnatural for children and teens.
