Managed to go into this without any-trailers/spoilers/etc. Hated the “Children in Need”-esque intro, it felt like the ye-olde cartoon before the movie starts.

I can understand concerns about this being the second of only three Tennant/Tate episodes, that it’s the anniversary and we want big celebrations and megabucks worth of explosions and monsters and all that. Instead, we get a full episode with the two stars and their talent, no distractions or crawling through attics. PS. Sylvia and Wilf still - and always will - be awesome.

This was like RDT’s and Moffat’s lovechild, like Midnight and Event Horizon and Alien. Confidently slow-paced with great writing and time for running around, and still having time for a proper ending rather than a magical macguffin arse-pull.

Properly loved it.
