The quantum of solace as to the CBS Home Entertainment September 17, 2019 DVD release of the seventh and final season of The Tiffany Network procedural "Elementary" is that it seems that incarnations of dynamic duo Sherlock Holmes and Dr. Watson are even more immortal than the fictional Victorian Era pioneering consulting detective and his colleague, It is logical to deduce that another film or television series featuring the exploits of those 19th-century gumshoes will be released in the not-to-distant future.
The highly entertaining and clever "Elementary" can be considered an even more neo-modern version of the Arthur Conan Doyle creations than the excellent BBC series "Sherlock."
The "Elementary" updates include transforming Dr. John Watson into Dr. Joan Watson (Lucy Liu). In addition, this sidekick who traditionally is a roomie turned partner-in-crime solving is now a sober companion turned apprentice turned full-fledged crime-solving partner to recovering addict Holmes (Jonny Lee Miller). For his part, Holmes is outwardly more dark and damaged than his previous versions. Moving the action from London to New York City is another major change in the Holmesian style,
"Elementary" creator Robert Doherty takes similar awesome liberties with other elements of Holmesian lore while staying true to the spirit of the source material.
In typical procedural style, S7 picks up in the wake of the S6 cliffhanger. A "send him back" sentiment results in Watson now being the stranger in a strange land when she and Holmes become neighbors at 221A and 221B Baker Street in London. They also get a sense of new-boss-same-as-the-old-boss on offering Scotland Yard the same consulting detective services that they had been providing the NYPD.
The shooting of NYPD Captain Thomas Gregson (Aidan Quinn) sets the underlying S7 action in motion. This begins with Holmes sneaking back in to the US to solve that crime. Stating that the agreement that Holmes subsequently enters to regain his legal status here is a deal with the devil is not far from the truth.
Discovering whodunit is only the beginning of the story; learning why he dunit ties into the aforementioned larger picture. Holmesphiles easily recognize the significance of Mark Zuckerberg fictional counterpart Odin Reichenbach (James Franin) the arch-nemesis of the final season. Yes, Reichenbach does cause Holmes to take a fall.
This unifying element is that literally evil genius Reichenbach is using his access to the online activity of virtually the entire population of the "civilized" world to (ala the Tom Cruise film "Minority Report") target what Reichenbach considers highly probable imminent killers of innocents. This includes a young guy who is planning to McVeigh a ferry.
The rest of this prologue to our story is that Reichenbach keeps his hands relatively clean by radicalizing traumatized "innocents" to do his dirty work. An example is a teacher who has survived a school shooting.
Holmes soon figuring out the scheme does him limited good; like all foes who have presented our hero with a real challenge for roughly 150 years, Reichenbach is just as much of a chess master as his foe.
This plays a hand in several cases, such as an early one in which the stabbing of a runner leads to uncovering a well-planned plot to take out someone on the blacklist of Reichenbach.
The inevitable showdown (with the predictable outcome) between Reichenbach and Holmes comes in the penultimate episode of the series; those who know the lore best are not ready to declare game over.
The series finale nicely delivers on several levels. We see Little Joan happy at last with a state-of-the-art existence that includes both professional and personal contentment. A blast-from-the-past in the form of Watson getting a gift for Holmes from foe Jamie Moriarity followed by the messenger essentially getting shot sets the stage for the final intrigue and the last chance for those who are left standing whom we have come to know and love over seven years to live happily ever after.
This discussion of the finale sets the stage for one more logical deduction in the form of the showrunners knowing that Hell has no fury like a fan scorned as to an unsatisfactory series conclusion.
