You don't even have to be fluent in Dr Who (which I am not by any means) to enjoy this one. You weave just the necessary references into the narrative so seamlessly.

This one is clever and funny...and ultimately a bit heart-choking, just enough of an ambush of tone change to catch you up short. Beautifully done. And Ancient/child Adam reassuring the Dr for his date with destiny was the final touch, Yeah, Stetsons ARE cool!
