Buzzfeed article -- "
"Sherlock" Fans Are Not Emotionally Prepared For This New Mini-Episode."
The first five things it mentioned, I'm all good with. The Canonical fanwank (the Head Lama in Llasa, the parsley in the butter, the Trepoff murder case, from EMPT, SIXN, AND SCAN respectively) was layered on so thick I needed a towel.
But then when it gets to Watson, it runs off the rails.
Yes, what happens at that point has charm. But it also doesn't make any sense. Because either Sherlock was such a tactician that he could fight chaos theory to such an extent that random encounters two years hence would fall into his plan, or everything we saw was simply a coincidence that humans with their tiny little brains could make patterns where none existed. Plus, the coincidences aren't aimed at the characters in-universe, especially the wink at the end; they're aimed at the audience, breaking the fourth wall.
That's really my problem with it. Whoever wrote this (Moffat? Gatiss?) chased suspension of disbelief down an alley, mugged it for kicks, and left it for dead.
I feel churlish for criticizing it, but like some of the
Doctor Who minisodes, it's very well made and entirely superficial. I enjoyed watching it, but when I thought about it and rewatched it, I didn't like it very much. The magic was gone.
