It's an episode of the show "Sherlock" which I haven't seen but I'm pretty sure is not an anthology series or "stand alone" type movies. It has the same characters and cast from episode to episode.
My primary reason for viewing "Sherlock" as worthy comes down to length. The episodes are 90 minutes, far exceeding a standard TV series, and fitting snugly in the perameters of an average movie. I can't be the only person who thinks so, considering "Sherlock's" award nominations include "best TV movie". Just because some of them continue storyline is beside the point, if that were a disqualifier, then we would also need to consider merging movies like "The Hobbit".
id vote for users to be able to opt in/out from that separate count. id prefer not to contaminate my search with stand-alone eps of same tvseries...like imagine u want to find some new series...and your search results are blackmirror 33%, cartoons/anime 33%, documentaries 33%. *huh!? closing criticker, deleting account* jk
