So this is the new trailer for the new season - the 32nd one! - of Doctor Who. It's all a tease. Primarily we just see some hokey clearly-not-from-the-series footage (As opposed to the normal hokey footage culled from the first few eps) as a way of selling us on excitement and hot chicks in short skirts, without letting out any spoilers.
While that's a clever idea and all, in actual practice it looks more like a bad music video, or an even worse perfume commercial. Frankly, it's the kind of thing that would scare away all but the most addlepated of 12-year-old girls who are like totally into their nonthreatiningly chaste gothy vampire thing, but totally don't dig the goth music scene and are still into ponies n'stuff.
So let's not tell anyone if we like it, ok? We've all got reputations to uphold
