This show takes itself very seriously and has no sense of levity at all. Part of what makes Star Trek stand out is the optimistic vision of the future. Removing that makes it feel like generic SciFi.
People in the penal system wouldn't be called "garbage" in an enlightened future society. That was totally unnecessary as was most of the animosity between characters. You can have conflict between characters in Star Trek, but just making everyone an a-hole for the sake of it is stupid and pointless.
Just like the a-hole Starfleet guard in Star Trek III, would made a point to mock Sulu by calling him "tiny"?
