Editing and Cinematography are always a crutch to a film whether it being a movie or a show. I do not mean that as an insult, but more of a fact. I fully support editing whether it is excessive (done well at least) or subtly. But when you think about it, it is not just Editing, it is also the use of cinematography.
I am going to dissecting both Cinematography and editing separate.
Editing:
Editing alone is fundamental in film and photography. No matter where you go in media there is editing. Now what people are trying to get across in that edit of the original product. The example that was used in the video was showing a compilation of moments when Sherlock was deducing clues or memories in his head. It was not just a simple flashback or sudden realization but you saw the process within his head. Something that if it has been done before, is very rare in television. The way you follow along with Benedict's Sherlock through the deducing is beyond captivating.
I personally loved the examples that they had used to explain how editing can be used in the way that it is in Sherlock. If more detective shows used the same methods as Sherlock does, maybe there would be more originality.
Cinematography:
Cinematography is not the only other fundamental element to a film or different media. It shares just as much importance with editing. As the video also showed, editing cannot be done without footage. Cinematography is the use of angles, shots, however you want to say it. In order to get those beautiful edits to even exist you have to have every shot possible. having every shot possible gives you more to work with to get those beautiful edits.
From experience in editing and shooting footage, it does work very well.
