The Coens are at their best when they're creative -- when their creativity trumps their self-indulgence: Raising Arizona (1987), Fargo (1996), Barton Fink (1991), No Country for Old Men (2007).
The closest they had come were the modern stories "No Country for Old Men" and "Raising Arizona" because they had settings in the Western United States and "The Big Lebowski" because it had Sam Elliot in a featured role.
“True Grit” isn’t as out-there as “The Big Lebowski,” as goofy as “Raising Arizona,” as bleak as “No Country For Old Men,” or as twisted as “Fargo,” but it crackles, like a good campfire, with colorful Coen flourishes all the same.
Yes, the Coens have engaged in remakes before (“The Ladykillers,” and, arguably, “Miller’s Crossing,” a version of Dashiell Hammett’s “The Glass Key”), and they’ve made a number of noirish films that feel like they could have been dressed as westerns without much alteration (including “Blood Simple,” “Raising Arizona,” “Fargo” and “No Country for Old Men”).
Thus, they followed their auspicious debut, the Texas-set neo-noir Blood Simple (1984), with the antic, cartoonish comedy of Raising Arizona (1987), which was then followed by the elegant gangster drama Miller’s Crossing (1990).
If their " Raising Arizona " showed the boys to be inheritors of Tex Avery, the finale of "True Grit" shows them as inheritors of F.W. Murnau as well.
