You can tell that Deep Space Nine is dark & gritty Star Trek out on the boundaries of the Federation's control where imperfect people have to make imperfect choices in imperfect situations. It's because they don't have a conference room. The conference room is the beating heart of a Starfleet crew. It's where everyone goes to respectfully share different perspectives and talk through challenging problems before agreeing on a mutually-acceptable solution which makes use of all their diverse skills. And DS9 doesn't have one! Because it was made by the Cardassians who don't do things that way!
