I certainly think they possibly had to squeeze two series into one, because of them coming to a possible end..
But I actually agree with Mark on this one: we are an intelligent audience, we don't need everything spelling out to us.
For me, as Liberty said, it's the little things that make it.
The slight squeeze of the hand, John's reaction when Sherlock acknowledges John as family...no words necessary.

But can we agree it's happy at the end?!
It certainly gains momentum.

No, I didn't think Sherlock and Eurus actually play the Sherlock theme (just that we know it's coming, so it puts a positive slant on the rest!), but even before the transition it sounds kind of positive to me.  And what we see on screen is more positive too, if moving.  I was quite surprised to hear that it was supposed to be the saddest piece ever!   It's a lovely piece of music.  I wish it was longer.

It's definitely a lovely piece of music and I agree, it doesn't sound like the saddest piece of music ever, maybe David and Michael decided not to take Sue's note on board haha.
 

Ok, so maybe she said saddest piece of music at the start 

No I didn't go to Steven's talk.
