Alixz, if that is the episode I am thinking of, I saw at least some of it on my recent Euro visit. I did not care for it. Rather sloppy I thought. And, I have no problem updating the story, it has been done many times. But, Holmes with nicotine patches ? Really, that was NOT his problem with dependency. If anything, tobacco would be the lesser of 2 evils for him.
And Watson a de-frocked doctor ? If I recall correctly, there was an issue with the doctor's medical career, but it is a stretch to put it in the Afghan situation. IMO.
I admit loving British mysteries, anything by Agatha Christie plus SPOOKS, MIDSOMMER MURDERS, JONATHON CREEK, et al.
Most of the do not get to the USA, Tim may know about what gets shown in Canada.. So far, it seems he sees the same junque we do.
