Up to Heaven and Down to Hell

The depiction of MS in this episode is ridiculously insulting. "Detected in the early stages" my ass! MS (and other auto-immune conditions) take 3-5 years to identify. This soap-opera BS depiction is an insult to my wife's memory and suffering. The writers should be ashamed.

As stories go this episode was not a real standout, except it delved into the human relationship of Captain Gregson to quite a degree.

There was nothing in this episode about the through plot of Sherlock's father's attempted assassination, so the 'human' factor was given to developing a story of Capt Greyson's social involvement with a former detective.

We are well into the 4th season and by this time writing/production teams will either go with the flow and keep the successful formula of a show going to keep audience and ratings, or they will delve into the unknown to see how far they can take it into challenges unforeseen.

With the time limit of hour-long episodes any time taken to flesh out character development is time taken from solving the crime of the week. So the artifice of exposition comes in handy to get to the resolution of the crime, as in this case, in order to bring down the criminal.

Some fans would wish to see Moriarty again, as dastardly superior criminals often get better written stories, but the introduction of Morland Holmes is a good distraction.
