I think I felt like this had a similar ish problem to recent seasons of The Crown - portraying recent, well known events, not really having a perspective other than "journalism is a very good thing!", and losing power dramatically as soon as the interview came round. I did enjoy it, funny in a few places, but still I wondered what was the point a bit.
Gillian was pleasingly camp as tits despite not bothering at all to do Emily's voice and Billie remains a star who deserves a proper vehicle of her own again soon. 6/10
