The build-up to Malcolm's downfall throughout this series has been fantastic. The dramatic tension really differentiates it from the first series, and it's definitely moving into tragicomedy territory. David Haig's character was just horrendous. I loved his line about Malcolm going "from Simon Cowell to Piers Morgan". That was probably the funniest line of the episode for me. "Obsessive Repulsive Disorder" sums him up perfectly. The rapport between Haig and Capaldi was amazing. If Capaldi doesn't get acknowledgement at the BAFTAs for his performance, something is very wrong.
I can't believe how quickly this series has gone by. One episode left. blah.
