I play Star Trek Online, where, during the first season the game devs introduced the four Lower Deckers are duty officers that you could get for your Federation captains, and I really, really wanted Lower Decker duty officer options for the Klingon faction captains, so was eager to see Klingon 'Lower Deckers' on the show for purely selfish reasons, but it was even more fun to see Vulcan Lower Deckers, and even Borg and Pakled Lower Deckers. (Now I want to see Romulan, Cardassian, Jem'Hadar, Orion, Ferengi, etc. Lower Deckers, just for the laughs.)
I did kind of hope they'd more obviously parallel the Cerritos gang. Just as 'our' Lower Deckers are three humans and an alien, I would have liked the Klingon Lower Deckers to be three Klingons and an allied alien (preferably a Gorn, but a Nausican or Lethean could work) as their 'Tendi.' It was great that one of them was stuck on 'Targ handler' duties for the day, since that was totally my idea for one of the less popular jobs on a bird of prey. Having one of the Klingons be 'the Boimler' and be a stickler for tradition and honor and impressing the officers, and another be 'the Mariner' and be more gung-ho and 'whatever works' and contemptuous of authority could have been amusing. As it was, the four Klingons came off a bit same-y to me.
I am loving that there's a Tamarian on the ship. Darmok was one of my absolute favorite Next Gen episodes, and it's fun to see them continue on.
Now I just want to see a Binar dyad, either in sciences or engineering! "It's so unfair, they get two bunks!" "Well, there's two of them." "But they're one person! They're small, they could totally share! And I was storing my stuff in that extra bunk..."
