I watch a lot of reality TV. I refuse to call it a "guilty pleasure" because I hate that term. Why should I feel guilty about pleasures that merely lack social approval?
Though, to be honest, I think reality TV can often be quite morally problematic, so, perhaps, in some cases, the phrase aptly fits. Though I'm interested in the moral problems with reality TV, that's not my main focus here (I have already brought up some of those issues when I discussed the fictional TV show about reality TV, Unreal (here), also see Mona Rocha's take on HGTV (here)).
Here I'm concentrating on a facet of reality TV and documentaries that bugs me. What I have in mind is the way in which the televising of the reality necessarily distorts the reality without any acknowledgement of that distortion. Let me explain.
