I've mentioned a few times now the importance of post-production and filming techniques, specific to the last couple of episodes but also the early Moriarty reveal in TGG. So I wanted to share this video which is a breakdown of Sherlock's revelation that CS is a serial killer. Check out how much can be revealed in under 4 minutes, and compare to the many minutes of time and repetion spent on other scenes. It's all priming, and this video shows Sherlock experiencing that very priming.
