The main idea of the podcast is that to say a "British" accent is too general. Harry and Hermione have a Received Pronunciation. Daniel Radcliffe is from London, but Emma Watson is from Oxfordshire - she learnt her form of speaking at a private school, which is why it is called "Received Pronunciation". I come from Australia (they have a horrible accent!), but I learnt Received Pronunciation when I went to live in England. So, Marina, I think you want to say that you love Received Pronunciation.
