First (and the reason behind my reluctance to date) is the huge quantity of plain crap.
Second, the large number of channels devoted to property. I don't mean creative or useful programmes like Grand Designs or Property Ladder, or mildly entertaining like the many variants on Location Location. The ones I mean seem to have no purpose other than promoting envy - 'this house is huge, way out of your price bracket and you are never ever going to get anywhere near it."
Are people really interested in the grotesque ego trips of some unknown rapper, or the often hideous monstrosities erected in sunny locations across the world? I know I can turn these programmes off, but the poor unfortunates who have to see these things every day don't have that luxury.
Third, the huge quantity of plain crap (yes I know I have said this already, but there is just soooo much of it...)
