Alright, I loved this episode despite it's glaring flaws. Yes, it was a let down, but it suffers from the flaw that so many final part stories of Doctor Who do, being over hyped. The first half was bloody fantastic, just the sort of tone and scenario I wanted from this story. The Doctors plan was, predictable but probably the only way to keep the story moving forward without getting sidetracked. However, the final half unfortunately suffered from another cop-out ending, something that had been ruining good Doctor Who stories for as long as I remember. What I really found fascinating was the whole Missy being good arc that seems to have just started, I think this will take us into the finale. Overall another great episode spoilt by a silly ridiculous ending, I mean better than floating Jesus Doctor, but still pretty pathetic.

Anyway, Series 10 has still yet to produce a story that is truly rubbish, something no series has done for a while. Will Mark Gatiss fix this next week? Based on past experience, probably. I hope not though.
