I thought it was an interesting episode. I mean, it seemed like it was trying to similar to the first episode of Sherlock in the latest series, in which there were a lot of references to appeal to the fans? Clara getting hit in the face with a paper, 'it's times like this I miss Amy', Jenny applauding Clara standing up for herself?

I'm still not sure. I like Peter Capaldi though, Normally the different Doctors are slightly different with their mannerisms and personalities but I kind of felt like Capaldi was channelling some Matt Smith especially at the end, which I realise is more for Clara's benefit than anything else but now hopefully she's accepted the regeneration (I mean Rose coped so much better with it! - I haven't watched a lot of the series)
