The main thrust for those who aren’t keen on our LGBT Sulu, seems to come down to two things. Firstly, why Sulu? It’s a good point, I mean it could have been anybody: Kirk is a pansexual fun seeker; who knows why Bones got divorced? Nobody said Spock and Uhura were exclusive; Chekov is just permanently horny and let’s face it, there’s more to Scotty and Keenser than meets the eye.
The fact is, we chose Sulu because of George, there was something sweet and poetic about it. Introducing a new gay character had its own set of problems, as I mentioned before, the sexuality of that character would have to be addressed immediately and pointedly and the new characters in Star Trek Beyond have enough on their plate, without stopping to give us the intimate details of their personal lives. We were concerned it might seem clumsy, tokenistic or worse, too little too late, raising and exasperated, “finally!” from those who’ve been waiting for representation for the last 50 years.
So why persist when George Takei wasn’t keen? The thinking behind embracing an existing character was that it felt as though it retroactively put right something that had long been wrong. By the time, we mentioned it to GT, the idea had taken shape, it felt good, interesting and worthy of thought and conversation.
We were disappointed that George didn’t see it that way but, truth be told, Sulu Prime seemed to be missing a very important point. With galaxies of respect to the great man, this is not his Sulu. John Cho does not play a young George Takei, nor does he play the same character George Takei played in the original series. He is a different Sulu.
