It's a very fertile time for surveying the Sherlock Holmes landscape.
No major Sherlock is currently holding the field. Cumberbatch seems to have faded a bit from absence and that season four collateral damage. Miller is heard spoken of even less. Brett seems to be rising just because the fans who never left him are more audible in the lull. And Downey? Those movie release flashes of popularity are hard to factor in, as he's both in the far past and the far future.
When no one Sherlock is dominating, all of the Sherlocks pop in and out of the Sherlockian landscape. It's a little like very slow moving weather patterns, looking at the ebb and flow of popular Sherlocks. We each carry our own microclimates with us, of course, as we may take to a given Sherlock more or less than our compatriots.
One sees this comment or that pop up as some moment summons a callback to a given Sherlock. Sherlocks are defined in their best or worst moments, depending upon our particular leanings. The truth of the matter is that we probably need ALL the Sherlocks right now. Whether one goes by the motto "No Holmes Barred" or "All Holmes Is Good Holmes," there is a basic need that Sherlock Holmes satisfies that might be needed more than ever right now. What need?
That people will actually listen to a clear-eyed smart person, maybe?
That someone out there can see through all the "There's a hell-hound on the moor!" stories concocted by some evil shit for their own purposes, perhaps?
That justice exists, even if it's via ships mysteriously sinking with all aboard?
Yeah. All of those. Maybe it's good that no one Sherlock dominates the landscape right now, because we probably do need ALL of the Sherlocks. The phrase "seasons of Sherlock Holmes" can mean a lot more than years of a TV show, and the one we're in right now might just be the one we need.
