So you do indeed live in another universe. In THIS universe there are no Sulu episodes. There are a few character moments but they don't amount to even roughly sketching out this character ... which is less than Mayweather got.
By the way, my point is not that Mayweather is a better character just because he has more screen time and a better character setup. I like Sulu more.
It shouldn't be that hard to separate facts and opinions, not even when you have strong opinions and loathe e.g. all the characters on a show.
