Maybe I had too high expectations because of the endlessly exciting pitch of The Tenth Doctor versus Missy, but this was probably my least favorite episode of the series. Tennant and Gomez are game, as I expected, but the script is just dire. It feels a bit like Destiny of the Daleks, where Tom Baker and Douglas Adams tried desperately to make the dull material entertaining with lots of jokes. These actors are very talented, but the thing about the audio medium is that it's all the more noticeable when the story just isn't grabbing you. I needed some drama, or some atmosphere, and there's just an absence of anything, and that makes the glorious potential of this showdown all the more disappointing.
