Some months ago I rewatched Q Who. During this encounter with a completely unknown but obviously hostile race, Picard orders a meeting. And then I believe he has another meeting later on. I can't think of any better way to suck the drama out of a story than to constantly interrupt it with everyone leaving to have a long discussion instead of actually driving the story forward.
I think Q, Who
is one of the few times that the "conference room" detour actually works. Part of it is the exposition we're given and part of it is that Stewart and deLancie are such good actors that they can sell the peril of the situation even from the conference room.
Unfortunately, among the regular cast there just wasn't any other actor as talented as deLancie to play off of Stewart.
