SusiGo: Well, then we are back to the question of the thread. I have no problem seeing this as the end of the story, at least the origin story of Sherlock (and John). Wherever they go from here, if we get more seasons, will be a new start. The chapters/part about Sherlock's origin story, and becoming the Sherlock Holmes we know from the ACD-stories and other interpretations, is now over,. And we might, or might not, get a new part of their story. And I am fine with that.
I don't think they can say anything else about it, to be honest. I don't think neither Ben nor Martin wants to give a definite yes or no yet. I don't think either of them totally dismisses making a new seaons, but that they are both ready to look to other projects for a while, so they don't want to make any more Sherlock commitment at the moment. Something I completely understand. They are both rising stars, and have so much going for them, career-wise. I wish them all the best in their future projects.
Perhaps the dust will settle a bit some years for now, and everyone is ready to make another season. If that happens, I will be thrilled. But I am not waiting around for it. As far as I see it, BBC Sherlock is over - at least for now. And I am very much content with the origin story we got. It's new, it's original and it has some great characterisations and developments.
It's certainly not perfect, but nothing is. To me, the pros more than outweigh the cons.
