Lots to love in this story ultimately mixed story.

There is a fantastic setting. You get a real "other worldly" feel, despite this being a future version of Earth. The sets and direction look outstanding, especially the fantastic scenes of Victoria running from the Ice Warriors in the caves.

Leader Clint is one of several fantastic great one off characters and is very well played. They perhaps repeat the for/against computers argument too many times, but it does contribute towards a good plot point (and you have to take into consideration that this would have been watched over 6 weeks).

This story is seminal in its ambition, huge scale and adds another great monster (second story in a row!) to the Doctor Who cannon..

Jamie asking Victoria whether she fancied dressing like the other women in the base and her retort is another hilarious, memorable and light moment. I love this kind of character building.

The story has a great set up, but a weak ending. After 6 episodes you shouldn't feel like the ending is being rushed.
