What annoys me the most is the "I won't tell you what I know, just to make things complicated". I absolutely hate it. A version of it is "I won't ask you what I want to know, just to make things complicated." That's terrible and painful to watch. Especially when nobody but a complete psycho would react like that in a similar real life situation. I wouldn't, you wouldn't, and if you actually would, I would kill you.
Totally and it seemed to me like this was used for edgy realism in SGU whereas all it really is is a tv trope. When this kind of nonsense is presented as the drama itself it's very frustrating
