I love reading all the theories regarding Sherlock (BBC) but some people really do take it too far and/or too seriously. I don’t think Moffat/Gatiss ever go that far. For all their secrets and wool pulling it never ends up being all that complex. I think this is why some people have become so jaded with the series. It will never live up to those expectations, the plot will never be as convoluted as the things we churn out over hiatus so, you know, calm down and stop fighting over EVERYTHING.
