I came across this series on Netflix last week and decided to watch it all in one hit.
Entertaining, but I don't know how accurate it is.
Johnny Behan is referred to as the Tombstone Sheriff, and not Cochise County sheriff. The Earp brothers are referred to as "his" Marshalls, employed by him to keep law in Tombstone, whereas Virgil was elected Town Marshall with Wyatt and Morgan his sometime helpers. And there is no mention of Behan telling the Earps on the way to the OK Corrall that he had unarmed the Cowboys either.
But the biggest error was in the guns. Wyatt is seen only with his supposed long barrelled Buntline Special, a gun that was probably never, according to Colt records, produced. In addition Buntline was only known to travel west of the Mississippi once, in 1869, four years before the 1973 was introduced, so together with the lack of Colt records of his purchasing five long barrelled Peacemakers makes the story, first recorded by Lake in his 1931 Earp biography, legend rather than fact.
Add that Wyatt was known to carry a S&W Number 3 (I have a replica hanging on my wall in front of me as I type), and every handgun, even those in the early 1860 Earp childhood portions of the series, are 1873's with the rifles '73 and '82 Winchesters, makes me doubt the authenticity of the whole series.
Add in the hyped political situation (Earps and the townsmen being of one political party with Behan and the Cowboys of the other) and I would say it is entertaining, but facts some factual basis.
Still, it makes the point that the Wyatt was not the hero that he was made out to be in the decades after Lakes book.
