From the little reaction I've seen on my flist, I think I may be alone in this, but I really enjoyed this. At last, a Mark Gatiss Doctor Who episode that I like!
The claustrophobic atmosphere in the Russian submarine, the feeling of peril - and holy creepy reptile claws! Ice Warriors are suddenly really scary, like Alien scary! Not clompy monster scary.
I adored the characters, I liked the 80s cold war setting! I loved the fact the Clara felt out of her depth and afraid but also felt the need to prove herself and soldiered on!
I take back everything I've said about Mark Gatiss Doctor Who episodes. All is forgiven!
