Cumberbatch also heavily insinuates that we should be prepared for the end. Via Deadline:
“It might be the end of an era…It feels like the end of an era, to be honest. It goes to a place where it will be pretty hard to follow on immediately. We never say never on the show. I’d love to revisit it, I’d love to keep revisiting it, I stand by that, but in the immediate future we all have things we want to crank on with, and we’ve made something very complete as it is, so I think we’ll just wait and see. The idea of never playing [Sherlock] again is really galling.”
I think many of us concur with that last sentiment, B.
But it’s become clear that both Cumberbatch and co-star Martin Freeman have struggled to incorporate the show into their increasingly busy schedules. It’s especially wonderful to see Freeman receiving such well-deserved notice. The role of Watson is by no means flashy; on the contrary, it’s in many ways thankless. But Freeman’s straight man approach, and the heart with which he approaches his friendship with Sherlock, has transformed the role into the show’s lynchpin. And of course, his chemistry with Cumberbatch is unparalleled.
Now I’m depressed! Ah well, we still have a fourth season ahead, scheduled for 2017 on BBC and PBS. Maybe we’ll be in less of a hurry for its release now.
