If anyone knows what Gene’s vision for the character was it would be the man who played the character for over three decades. To reveal in this film that Sulu is gay would mean that he was closeted throughout the entire original series as Takei points out himself. That doesn’t really sound like something that would happen in Gene’s vision of the 23rd century does it? Again, something that Takei pointed out.
The character of Sulu is very close to Takei’s heart. The fan film World Enough and Time (Highly recommended) stars Takei and solidly cements Sulu as heterosexual. While not canonical, Takei is very proud of this production and more than likely considers it part of his personal canon for the character. For the filmmakers to approach Takei for his input/blessing on something that they state is meant to honor him and then completely disregard his wishes is disrespectful.
I agree with this. George Takei still honors Gene Roddenberry’s vision because he understands and respects it for what it is. Making Cho’s Sulu gay comes off more like a gimmick than anything genuine.
