(SPOILER)
I absolutely adored how smurfing creepy Capaldi looked. Like man, just suddenly there, and his big bushy brows and intense stare. As a recent watcher of the series I can't say too much else but I really appreciate what I've seen of Matt Smith and I think he did a smurfing phenomenal job. Lots of feels in that episode, even trout like the Cyberman head dying and trout. Obviously would've been way way better if we didn't know of Capaldi's existence but whatyagonnado.

A lot of the returning elements felt like they were shoehorned in ineffectively. Like, no need to hit us over the head with stuff: fans of this series are, from what I can tell, pretty smurfing savvy. They can tie up loose ends themselves (and some loose ends left are smurfing excellent imo). But yeah, I feel like this is a good time to get on the Who train.
