First thing I thought was that the ship was going to be in Academy Mode because it was obviously landed and not in space, which we saw earlier seems to be able to simulate just about any scenario. Which would also explain why it was accepting commands from cadets without question.
DS9 especially got one of the absolute worst fan reactions at the start. Primarily over the fact it wasn’t set on a Starship with a story of the week layout. History has shown it to be one of, if not the, best shows in most people’s rankings however.
Trek fans are some of the worst to get early feedback from honestly. So many just have kneejerk reactions and are defensive for no reason.
As much as I want this… It’s a complicated timeline, that would be right in the middle of all of the 90s trek shows.
Don’t forget the very first episode literally having Harry and Paris in Quarks Bar, and talking to Quark on DS9 before Voyager heads to the Badlands.
