It took me a long time to get through this one which almost certainly impacted my enjoyment. There was some solid characters though I wasn’t convinced on Jack Frost as a menace. Eccleston was on form as ever. Good mini-exploration of anxiety in one of the side characters, which felt very “Doctor Who”.

I’m now very behind on these sets - stories like Salvation Nine make me want to bound into the next one, but ones like these slow me down!
