Doctor wasn't there for a third of it, lengthy flashback in old filmic style, villain not revealed until the very final act, very little for Clara to do... it seemed, in a Night Terrors kind of way, like a hell of a lot of build-up, followed by a very speedy ending. I don't know! I thought it felt a bit bizarre. Lots of emphasis on weird images, not so much on plot. Good reveals, good jokes, interesting characters, beautifully filmed (the technique of the old filmic flashback was ace!) but it felt funnily-paced, funnily-plotted, and slightly missed the mark for me. Wasn't impressed despite everything, rather than because of everything. Even the things that should've been brilliant - Strax is hilarious, but he's repeating jokes from The Snowmen almost word for word. I don't know! Just didn't resonate. I love The Unquiet Dead to bits, but since then, Mark Gatiss hasn't quite written my kind of Who. I think his vision for DW is parallel to mine, but slightly to the left. Phenomenal writer, just doesn't quite work for me.
