This video is great because it takes a show that is usually fun and quirky and puts an interesting darker spin on it. One of my favorite parts of Doctor Who is the constant question of how much influence the Doctor should have on the course of history. Is he making the right decisions? Would the universe be better off without him? How far is too far? And should anyone have that kind of power? My favorite episodes are the ones that explore this fine line between good and evil. I think this fan video highlights this well.
