But there’s a lot of McGraw in s1 too,

Yeah, there’s a fair bit of McGraw in Season 1 Flint, too, but season 1 Flint is a cunning bastard at the same time with a kind of vast disdain for his crew, and I don’t see that in Season 4 Flint. I think that’s what distinguishes the two for me – McGraw cares about people so very much whereas Flint is all strategy and “the ends justify the means.”
