I saw Beyond this evening. Sulu’s partner is in the movie for something like 10 seconds. It’s almost literally “blink and you’ll miss it”. And really, in this very brief scene with them, there’s nothing (in my opinion) to definitively indicate they’re same-sex romantic partners … if not for the pre-release publicity, I think you could easily think they were just very good friends.
As for the movie itself, I enjoyed it. There’s some great interaction between Bones and Spock, something we didn’t get enough of with the first two reboot films. Scotty also has some good material (I would have hoped so, since the script was co-written by Simon Pegg, who plays Scotty) and I liked the alien Jaylah who helps our intrepid crew. Although if you didn’t like the supercharged action in the first two reboot movies, be warned, this one has more of the same.
