Apparently, people can be conned into watching virtually anything these days. Rather similar to Holmes in this particular bit of lassitude, as narrated by Conan Doyle, enjoying a regular injection of cocaine or morphine because he is otherwise bored with life (do pls read the first chapter of "The Sign of Four" before you author a disagreement with this observation).
Frankly, I'm somewhat amazed that the leftist producers of such tripe haven't seized upon the literarily correct opportunity to use Holmes as a medium for even more subversion of what used to be ordinary personal responsibility, by featuring the character's use of opiates and other chemical stimulants. Of course, this television production disdains presenting its re-creation of Holmes with any warts at all. Evidently, it escapes noticing that Holmes's assorted personal defalcations were a good bit of his charm to the reader.
