I quite enjoyed that episode, although I'm still waiting for a better episode- the stories this year are disappointing me. This episode was let down by the killer robot. For the universe's deadliest killer robot ever made, it looked extremely lame. And I think they must have been low on budget by this episode, because to me it looked like it was made out of something that was a lot softer than the solid metal we all expect our killer robots to be made out of. And the problem/solution dialogue was also very tame. If a story features the universe's deadliest robot, I want to experience a little of the fear that would happen if it was real.
