Sherlock series 3

After 2 years, finally this January 2014 we had the third series, which means episodes 7, 8 and 9.
The empty hearse
The sign of three
His last vow
these 3 episodes seem to me to be more concentrated on Sherlock's character and sentiments than on the crimes. In the first we see his return, and how John deals with it, and it's all about that, about their relationship and how Sherlock never realised how this would have upset John, and never imagined he could have a life of his own without him.
I still am disappointed at the fact that there was no real explanation about how he survived the fall. There are some openly fake, and then there is one that should be the truth, when Sherlock explains everything to Anderson. (I don't like Anderson)
I understand that the way Anderson reacts after that is irony at the audience thinking but but... unsatisfied with the explanation, still it can't be helped because it really was unsatisfying. First of all, he said he had not forseen that Moriarty would go as far as to kill himself, but I say that if he hadn't then Sherlock's plan wouldn't have worked, because Moriarty would have seen him texting and waiting for the reply, and also he could have looked down, watching him do it and seeing the trick. Of course Sherlock did tell him to give him some privacy, that's true, and Moriarty looked the other way for a moment, maybe enough for the texts business, but what about the actual fall? A Moriarty alive would have looked down to see him dying, don't you think? Then, he had thought about this plan in advance, but thought of Molly's help only at the end? She was important not only because she procured the other body, but mostly I think because the gave authenticity to his death, since she is the morgue pathologist.
Sherlock doesn't explain it to John, and that's another thing. Is he ever going to tell him? Or this is the only explanation we are going to get?
The sign of three is funny and touching, showing how deeply Sherlock feels for John, and finally showing John actually curing someone, saving lives! Hooray!
Again here they give the fandom a slogan, because Sherlock and John drunk was funny, but John saying "he's clueing for looks" has become immensely popular! John speech at the wedding was very long, but with very touching moments. I love that he doesn't understand why people have tears in their eyes, and he's worried he made some mistake, and I was watching it with the same eyes that Molly had, and I can't say how I love such a simple line from Mrs Hudson, when she said "oh Sherlock" so perfectly it felt as if I was now authorized to cry, I can't explain it, but it was beautiful.
In His Last Vow we see again how Sherlock feels different from other people and feels because of it. He hates Magnussen because he uses people secrets to blackmail them. He hates Magnussen more than anyone else.
In all three we see Mary, John's love, played by his partner in life Amanda Abbington.
