Only The Avengers could do a Christmas episode like this. It’s absolutely filled with wall-to-wall delights like a series of foreboding Christmas-themed dream sequences, psychics stealing state secrets, a Christmas party and spooky mansion both themed after the collected works of Charles Dickens, and a fucking hall-of-mirrors gunfight with Santa. And of course it’s got the show’s top-class costuming and production design. I’m reeling. Incredible stuff
