Seriously? Who is he trying to kid? I don't know if the show was always this way, but right now, it can go toe to toe with Buffy on the angst levels.

RTD has used pop songs pretty effectively before (I liked Last of the Time Lords especially), so I would flove a musical. In fact, RTD has written a lot of my favorite episodes; I do think he's a great writer; he's just terribly bad at endings. If he can write a musical without putting in some emotional trauma in the last ten minutes, that would be great.
