I saw "True Grit" last night, although I had sworn after "A Serious Man" I would never see another Coen Brothers film again--I had seen the same old black humor routine too many times. (I had not seen the John Wayne version, as I understand the Coen Brothers also had not.) I noticed no black humor here.
"True Grit" is just an EXCELLENT film. I recommend it.
What impressed me most was the EXTREMELY effective use of music in the soundtrack. Subtle, never overdone, and generally the extreme opposite of the way music is almost always done in westerns and historical films. The signature tune is "Leaning on the Everlasting Arms." It worked remarkably well.
