I agree, many scenes are written to be funny, not to be interpreted too much. That doesn't go just for Johnlock - I personally severly dislike the scene "Mary is taking me home" in TAB, as I don't see how bossing a man around is any better than bossing a woman around. I could go into a long feminism rant about it, but at the end of the day it's two seconds of humour. It's meant to be funny, not to write a thesis on it on feminism.

I guess we'll just have to wait and see whether that was more than just a joke.

I've seen all episodes of the TJLC series now (the ones that are out so far), and I was quite interested in the one about sexual imagery as there are quite a bit of that in the show. So I was a bit disappointed when the video mentioned a whole bunch of scenes that to me doesn't have an inch of sexuality hints in them at all. It read to me a bit like giggly teenagers who will think "sex" with just about anything.

And I don't think it's necessary - there are already quite a lot of sexual imagery in the series, there is no reason to overanalyze every little thing. That just fuels the idea that Johnlockers are in it for the sex. (However, I am willing to agree to being open about Sherlock perhaps having a military kink. I don't think that was intented by the writers, but if they wanted to do something that was subtle enough for the casual viewer to miss, but clear enough to not need overanalysing to get - this is the way to do it).

However, to not come across as only being negative, there are a few interesting bits in the series, and I found most of them to be in the very first episode. Talking about early interviews with the cast and crew, especially one where Ben said he was intrigued by "where the relationship with Sherlock and John were going" in this series.

That caught my interest because we already know about Sherlock and John being the best of friends, that can't be something Ben would find intriguing og particular interesting as that is already established and is the basis for the entire series/books/canon. 

However, I won't say for sure the only other option is romance - perhaps he is talking about the journey, and Moffat talking them both through things in a way that is different (more dramatic?) then what has ever been done before? (As far as I can tell, we've never had a renunion scene like that before in other adaptations?)

This is not a criticism of Rebekah, btw. She does a great job with these videoes, and explains most of it really well. I am only talking about the ideas and how I think most of it is prone to oeveranalyzing. But, as mentioned before, that is understandable and seem to happen with fandoms that have to wait. 

One should imagine ACD would have kept Mary in the stories instead of disposing of her with one sentence if she truly had been the love of Watson's life. And maybe she would have remembered her husband's name as well. And maybe the BBC team had not turned her into a killer. Just saying. 

We'll soon know.
But some people seem to have been disappointed by S3 in a way I never was.
My fave series.
TAB was the icing on the cake.
You'd think in  a personal mind palace anything could have been...but it seemed to me to more or less confirm everything in the previous 3 seasons.

I look forward to more of the same.

But it was supposed to be deep inside Sherlock's mind, and yet we didn't see Johnlock.  Which does make you wonder ...  how would they explain that if they ever tried to claim that it had been there all along?   I think they could start a romance in S4/5 (although I doubt it, because of what Mark said at Mumbai), but I don't think they could treat it as if it has being going on all along (whether acted on or not).   I know Johnlockers and TJLCers have seen clues all along, but the general audience hasn't.   If they want us to buy into a romance they've got to show us it, they've got to tell us what's going on.   And they haven't. 

I'm not the ACD expert that some of you are, so I never like to weigh in on his intentions, but I've got the impression from somewhere that he kind of made a mistake with Mary - it was a nice little romance in a particular story, but it landed him with a married Watson when he really wanted to write stories about these two guys together (whether as friends or lovers, either way!).   With Irene, it was very clear that it was a one-off story about one woman, and that it wouldn't be following through to other stories - which is why I don't really expect or want to see Irene back again (I felt ASIB had a similar "one-off" feel). 
 

I agree on Irene.
What is clear(to me) in Canon and in BBC Sherlock, is that Mary is the love of John's life.
So I just don't know where they'll go with him, if she leaves the series.
And btw, if I'm not allowed any more Jim, then I don't want any more Mary- so there!

I don't think it's clear anymore that Mary is the love of John's life.

- I think it's clear that John had romantic feelings for Mary before the HLV reveal.
- I think it's clear that John isn't happy with his newly-wed life without Sherlock
- I think it's clear that John wants to forgive and try to live on with Mary after HLV, but after the shot we don't see any scenes between John and Mary that show any of the happiness they shared before the shot (for instance, the bathromm scene in TEH). 

I think that if Sherlock had never come back and Mary had never been revelead to be an assassin, I think John would've been as happy with Mary as he could be without Sherlock in his life. As for what he feels for Mary now, and how their marriage will be, I don't think we know enough yet to say anything for certain. I am very excited to see what will happen with John and Mary in S4 because of all this.

I cannot for the life of me imagine them being totally happy. As Vhanja said, after TSoT we do not get a single moment of happiness between them. This also goes for the whole of TAB. And if we believe the two modern scenes to be real, they do not even speak with each other. Not a single word. 

Right. True love does not need words.
