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.
Doctor Who (2005)
1 plot hole in New Earth - chronological order
Visible crew/equipment: During the warehouse battle, around when the Doctor tells Donna, "Hold on, I'm coming", the film crew can be seen reflected in a door at the right of screen. (00:28:20)
Doctor: So, that's the trap. Or the test or the final judgment, I don't know. But if I kill you, I kill her. Except that implies, in this big grand scheme of Gods and Devils, that she's just a victim. But I've seen a lot of this universe. I've seen fake gods and bad gods and demi-gods and would-be gods - out of all that - out of that whole pantheon - if I believe in one thing... Just one thing... I believe in her.
Rise of the Cybermen (1) - S2-E8
Trivia: Only eleven Cybermen costumes were built, but careful filming made it look as if there were more.
Evolution of the Daleks (2) - S3-E5
Question: When the Daleks sabotage Human Dalek Sec and the Doctor's treatment to turn the dead human bodies into Dalek-Human hybrids, why does the Doctor not help Dalek Sec escape along with the other human prisoners? If he truly believed that Sec had changed (becoming less Dalek and more human), enough to voluntarily help him with the hybrid formula, then why not try and get him out as well?
Answer: Sec was killed and Diagorus wasn't connected to the same system as the dead human experiments. Also technically... Still a Dalek.
