Doctor Who (2005)

New Earth - S2-E4

Plot hole: Those people created for medical experiments cannot run. In fact they can barely walk, so how come they can climb nearly as fast as Rose? What's more, when you see them climbing, they seem to have little ability to coordinate hand over hand. Even with the delay brought on by the cat-woman-thing, they should not have been able to keep up with her.

The Impossible Planet (1) - S2-E11

Plot hole: The Doctor and Ida are stranded 10 miles down, and yet the lift travels very slowly, like walking pace. They only have an hour's worth of oxygen left in their suits - by the time they get to the surface, it would have run out.

The Impossible Planet (1) - S2-E11

Plot hole: The rocket flew down a gravity funnel and (presumably) crash-landed on the planet, since the true Captain died during the landing. The rocket is big, but surely not large enough to contain all the 'flat-packed' materials for the sanctuary base (which is massive) and the gantry which supports the rocket. Where did that gantry come from? It is the same size as the rocket. It is not possible that the sanctuary base and rocket gantry could have fitted on board that rocket.

The Satan Pit (2) - S2-E12

Plot hole: At the end, the Doctor bumped up against the TARDIS in the bottom of the pit. There was no evidence that it could have fallen that far, especially through the sealed entrance that didn't open until the Doctor and Ida were there.
