Thank you kc, we found a review of this that made us want to see it:
I've always got more than a hint of homoeroticism in this re-working of the Sherlock Holmes mysteries set in modern London. In this episode Sherlock makes clear that he is in love with Dr. Watson. Yes, but that's nice to see.
Really, this is the BBC at its very best! It is an excellent drama which also has a homosexualistic tinge to it. Sherlock tells Dr. Watson "I love you". I think we already knew that.
It is written by two homosexualistically inclined men - Steven Moffat and Mark Gatiss. Do you need any better recommendation? Let me be clear this film is not an "in-your-face-homosexualistic-film". But, all of the hints pointing to the homosexualism of the leading characters are there. You just need to be able to recognise them. Enjoy it, gentlemen.
It was good, Sydney, but not very good at all! Let us hope that The Final Problem will be better!
"In the final episode of this series, written by Mark Gatiss and Steven Moffat, long-buried secrets finally catch up with the Baker Street duo. Someone has been playing a very long game indeed and, alone and defenceless, Sherlock and Dr Watson face their greatest ever challenge. Is the game finally over?"
