This was a massive episode. Not only were the stakes enormous and the cliff-hanger whopping, we were treated to perhaps the biggest assembly of Doctor Who baddies the show has ever seen. Not just fifth season villains, either—we got to see Autons, Cybermen, Sycorax, Daleks, Judoon, Sontarans, and a whole host of other nasties too numerous to mention (except I do mention them later). It was like fanfic times 10 to the power of 23 (I did the math). I also totally had several nerdgasma.
