And why is this allowed? https://www.criticker.com/tv/The-Reichenbach-Fall/
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".
