I hated this BBC series and couldn't watch more than half the first episode. Though I don't agree with Germaine Greer's views on the PRB, I think her remark:
Although one might agree with Franny Moyle, author of Desperate Romantics, and with whoever it was at the BBC who decided that the TV series should have the same name, that the pre-Raphaelites were desperate, the notion that they were romantic (whether you spell it with a big or a small r) is nonsense. Not that anyone at the BBC cares; the intention was to smuggle pretentious pornography on to the small screen in prime time and get away with it. Job done.
