This story feels like a stepping stone to something better down the road, it's very middling and forgettable but it just feels like remix of the last story that only exists to introduce our companion character Cole.  Jacobi is great as always and Cole seems likeable enough, but the paper-thin plot and poorly realized themes and ideas brings it down significantly.

Okay, this one was a bit odd. I know it leads on from the events of 'The Devil you Know' but I kinda felt like this one was a step down. By no means was it bad, but it was just alright. I can't particularly remember most of this story, but I still didn't mind it. The introduction of Cole as a companion for the Master was a nice one, though.

Decent story, got a little lost at the end though. Still warming up to the war master though, it's quite an adjustment from stories with the Doctor.
