"Sherlock" season 4 has finally ended its fourth season. It is possibly the end of the entire series entitled "The Final Problem" wherein Holmes and Watson were placed through an emotional wringer and also were able to explore their mysterious childhood. The final episode has also set the stage for a more traditional version of mystery tales.

As the season 4 ended, showrunner Steven Moffat had explained the intense and conclusive finale of the show. According to him, he doesn't know how people will blog about how evil he was but he was just proud of anything he does. Moffat added that he loves the flow of the plot wherein there is a final sequence running around where he tries to stop the plane crash or solve a puzzle, and saving John Watson from drowning was a lot of fun for him, EW reported.

Further, Moffatt added that this has been the first time for them to end a season where they try to think whether they come back or not, it will still be fine. As he said, as endings go, people will just say they carried on solving crimes on Baker Street forever. They are also not allowed to end Sherlock Holmes and thus, according to him the only ending they could ever have is, "And the legend continues, forever and ever."

On the other side of the story, Nolan's influence has definitely transformed "Sherlock". It has been revealed on Sunday wherein a supposed to be detective drama was turned into a superhero origin story.

It even completes a childhood trauma, terrifying villains with supernatural powers and it was shown in the final showdown that an ancestral home was burned. In the season 4 ending, the BBC show has turned its main characters into superheroes and even lost everything that made the show special in the process, the Atlantic reported.
