An improvement on last week's...whatever the hell that was, but still nothing remarkable. Basically a cross between Aliens(s)
, The Hunt For Red October
and the first X-Files movie, with an Ice Warrior thrown in for good measure. Clara still does nothing whatsoever for me, and having her save the day with her speech and "singing" was a bit much. Still, Smith is always eminently watchable, David Warner is generally good, and it was nice to see an Ice Warrior again (as opposed to the done-to-death, turn-up-so-often-they're-boring-beyond-belief Daleks and Cybermen).
The best of the three to date, but given how crap I found the first two to be that isn't saying very much at all.
