I always thought that reality tv was the worst thing to happen to BBC. Then I realised I'd been wathcing almost religiously 3 BBC reality TV shows, that were actually pretty good.
1 Dog Borstal. I don't own a dog, I don't intend to own a dog. But a show about real people brought together, by nothing more than their ability to control their pets. It's weirdly epic and moving, I never knew I could almost be moved to tears. By a labrador getting over it's poo addiction, or a little Jack Russel beating sex addiction. Mick Martin is also very funny, in a natural unscripted way.
2 The restaurant. Damn this is a classy and weirdly serious show. A reality show about real people trying to get to run a real business. Raymond Blanc is also the most polite person on TV, whilst being about a 1000 times scarier than Alan Sugar.
3 Last Man Standing. 6 athletes join people in the developing world and compete with them. It's simple and enlightening and also weirdly real. I loved at the end of last season when they decided who won by having a polite chat. The tensions around the contests though is quite real.
