This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: Shadow Planet

I quite like how after complaining about the lack of character stuff in the last story we get a story that is entirely devoted to, well, character stuff. Ace and Hex get trapped on a planet that magically disappears out from under the Doctor's nose a la The Stolen Earth. It's a really great way to explore Ace and Hex's relationship with each other and their view of the Doctor, particularly Hex.

Philip Olivier gives what I think is his best performance yet as Hex (granted I haven't done all of his stuff) and you can really feel the rage and frustration at the Doctor for taking his time rescuing them just to keep the sentient planet alive. It's a really interesting way to challenge the Doctor and quite an interesting story as a whole.

I think the only issue is that as this was made after the fact for the Ace/Hex arc what should be a really important event for Ace and Hex can't really be explored and expanded in any other stories. It leads to Ace being a bit too uncaring about what she's just experienced and she forgives the Doctor a bit too quickly in my eyes.
