I guess most shows that need to have the drama built up have one or more of their characters carrying the Idiot Ball(tm) for longer or shorter periods, up to and including always. I know that's why writers do it, but it really makes me wonder how much of the viewing audience doesn't mind/care, and how much of them/us hates this convention. Case in point: characters not sharing information where common sense would seem to indicate it's vital information that everyone else should know right away. It makes the bearer of that information act not at all like a sensible human being in that particular regard, and is quite irritating. But, like the road rage I ditched long ago, this is one of those things that apparently is never going to go away or get better, so I'm (still) learning to shrug my shoulders and try to move past it.
(looks at what's been written so far) Judging by the size of my rant, I'd guess it's still somewhat of a problem that detracts at least a little from my enjoyment of many TV shows.
