Psychotic About Wand Erection?

Unless you live under a rock, you may have seen the show or at least heard about the Channel 4 documentary, called "Crazy About One Direction" (checks for Simon Cowell threatening a Take Down notice again).

I'm not a fan, I don't like their music, I don't find them remotely attractive. 

I, however, was well into Take That back in the nineties. So, I do understand that the band are going to be beloved by girls of a certain age. Teen fandom is as old as The Beatles after all, it's nothing new.
