It is mostly worrying only because Picard is in the production at the same time, and one should hope that they will be having some era appropriate ships, and by all reason Short Treks could have used those. That this didn't happen raises concerns about the production deign of Picard, which is a much bigger deal than this mini short.Speaking as somebody who's been involved in the fan film production process I know that a very limited running time combined with budget constraints can present challenges in creating visuals. Sure, CBS has a metric ton more money than a fan film production team will ever have but the situation is similar.
Eight minutes, at least two of which is credits. Almost every scene takes place inside a building. One brief scene of two starships in drydock orbiting Utopia Planitia was not going to get the royal treatment from the CGI effects team. I don't like seeing them either, but nobody is going to pour that much resources into one brief shot in a short film that has a briefer running time than some experimental student films or YouTube rant videos about TROS.
I'm pretty forgiving about this. I wasn't expecting grandiose visuals from this thing.
