movies/tv Doctor Who Sequels?

[Pentakill 68]

I was watching Doctor Who 2 (the new series) the other day, and I came to the episode called "Midnight".  I like that episode because it starts to mess with your BRAIN!!!! I just think that there should be a second episode (a sequel) about the planet Midnight.  I just want to see an episode where The Doctor goes back and figures out what that creature was, and try to stop it.  I just feel like they didn't go deep enough into that subject.

 

My question is does anyone else have a Doctor Who episode that they would love to see a sequel of.  Do you guys have any subjects from the old and/or the new series that you felt they didn't elaborate on as well as they could of?  Just tell me your thoughts on that note.

 

Here is part of the episode "Midnight" for anyone who doesn't know how it goes.

That episode was wonderfully creepy in all the right ways. It wasn't even setting out to be "Scary" for the sake of scary. It was engineered to make the viewer wonder what's going on and propose hypotheses in order to generate the desired emotions. Brilliant. But yes, the episode was never truly explained, and everyone onboard was just trying to do whatever they could to survive, rather than find out what the thing really was and where it came from and of course, how it was actually doing that. Especially when it took over the Doctor.
