Man, as much I love Dalek, I have to give it to Empty Child/Doctor Dances. Top 5 story of any era. As close to perfect as any revival era story has ever gotten. I love how watching it for the first time and then rewatching it feel like completely different experiences (first time, you’re sacred of the Empty Child, but second time, you’re scared for him).
I also just love how sex-positive it is. Pretty much every scene in some way relates to sex, either the act itself or the results of it (procreation, social dynamics, even abuse in a way that doesn’t derail everything else around it). As much as I understand the stance that the Doctor is inherently asexual (Eleventh is my Doctor and he is absolutely that, so I definitely get the appeal), there’s just something about establishing Ninth as full-blown bi in this two-parter that’s part of the reason he’s one of my faves.
