"The Tester" makes me mad, more than a Reality show should.
Reality TV is, by its definition a hollow, bitter creature, a frankenstein assembled after the fact in the misguided attempt by producers and editors to make something "interesting". They make people out to be demons for our amusement. They toy with the hopes of participants who perhaps aren't aware of the backstage machinations already in play to make them fall before the stage is even set.
We, as a people, have decided we are okay with that. Despite the fact that the whole point of "Reality" television is that it's supposed to be... you know, REAL. Or real-er than, say, an episode of Cheers. They manipulate the order of things to make artificial conflict, because some sleazebag in a suit believes that's the only way to make "real life" interesting.
...Which the inexplicable success of cake shows has proven that no, that's bullshit, we really will watch any culturally worthless garbage, even if it doesn't have drama or shouting. If fiction uses lies to tell the truth, reality tv abuses the truth to tell bullshit.
