I don't sense that Uhura is overused, although she has slightly fallen into the "super genius" trope, because apparently it's not enough simply for a character to be a competent technician and proficient officer.
It's partly that. Uhura just seems to be involved in...
everything that happens on the ship. I also don't really know why Uhura has to be a Super Special Super Genius as well... I think characters really stop being an inspiration or representative when it's clear
you are NOT like them. I'm a straight dude so take my opinion her as you will, but it bothers me that they took a character like Uhura... who is someone that all women of color could look at it and say "that's me!", and turned her into a super genius character who now has really nothing in common with them aside from sharing a skin tone.
My main issue with SNW S2 is why we needed to bring in Kirk when we've already got a fine ensemble. Unless the plan is ultimately to handover.
Yeah there are enough good characters that we really don't need Kirk. Once was enough. Sure have him show up, "oh cool, it's Kirk", and then we're good.
Although even more than that, my issue with SNW S2 is more the somewhat overreliance on the humor episodes. In a 10 episode season, you've got three that leaned on humor... maybe closer to 3 and a half because I think alot of "Tommorowx3" relies on the "hurr hurr they're in TODAY!" humor.
I'm ok with humor episodes. It's actually on the other end an issue I had with Discovery... Discovery was always too superseriousgrimdark all the time. It's ok to have fun every now and then. But... SNW S2 probably should have picked ONE of those, and it absolutely should have been "Those Old Scientists".
If it was a 22 episode season... ok, do a couple goofy fun episodes.
