In case you missed it, I am reprinting Kendall J. Pagan's Sherlockian Pagan blog from last Monday here:
Sherlock Goes CBS?
Since Moffat and Gatiss frequently ripoff--er, pay homage--to Canonical and non-Canonical sources (the nod to The Big Lebowski in "His Last Vow"? Genius!), they could pay tribute to CBS, the network they ripped off when they came up with the idea of a modern-day Sherlock Holmes--I mean, the home of that blatant copy of Sherlock--by using the former lead-in to Elementary as the template for Series Five. Janine Moriarty kills Mary Morstan in a Quentin Tarantino-esque shootout, but the unborn baby is saved!
Yes, it's Two and a Half Sherlocks! John and Sherlock raise little Sherlock Jr.--Mary's dying wish for the baby's name as well as an oh-so-clever wink to Buster Keaton's silent classic.
Mrs. Hudson is already pretty much Berta and Nurse Chappell--sorry, Molly Hooper--can babysit, proving the feminine touch to the household while pining for the unobtainable Mr. Spock--Holmes.
As he gets older, Sherlock Jr., can join Da and Sherl on their cases; strapped to John's chest as they chase down Count Negretto Sylvius and Leonardo the strong man to retrieve the Black Pearl of the Borgias; he can learn how to deduce a maitre d's pregnant wife is calling before the mobile rings from Sherlock and the art of beating up one's best friend from John. Mycroft can play Uncle Scar.
Such a set up allows Series Six, Seven and Eight to write themselves and ensure the spinoff "Sherlock, Jr." when Cumberbatch and Freeman are too busy to make their tri-annual return. The spinoff can be a series of Christmas specials with Gramma and Grampa Holmes providing the presents and comedy relief.
Go for it, BBC!
