Plus, most fans on discussion boards agree that it would be better to delay the season as much as the producers need in order to polish it properly, as opposed to rushing it out the door just to make use of the hype.
After all, if they took that approach and had to sacrifice some of their production values in the name of completing the season faster, that would severely harm the show’s chances of getting another season.
With the rumored return of Moriarty and a few other developments that have been circulating in fans’ discussions, this is shaping up to be the most interesting season of the show to date. “Sherlock” took viewers by surprise to some extent when it first launched and the producers have managed to maintain their level of quality so far, and we’re as excited as fans themselves to see what’s coming up in the next season.
We don’t have any confirmation of the character’s return on the official front so far, but there are rumors about others – like Mary – being given a more central place in the plot. It’s also possible that we’re going to see some new characters introduced to the show in a more permanent way, although the producers have generally been careful with this and they mostly like to focus on their main cast.
