Miller's Crossing -
After watching the whole thing, I have the reaction that Andy does to NCFOM - good, but not great for me. After thinking about my question a bit ago, for me and the Coen's it must come down to the characters/dialogue, and that's what is not clicking with me and their movies. I am way more likely to like their dramas, but even then my latest rewatch of Fargo seemed to lose a little steam too. I don't think it's a coincidence that No Country is my favorite of them, since I assume it's one of the few of theirs that is from a source material. Then it would be Fargo, Blood Simple, Miller's Crossing. Not in a rush to sit down and rewatch many of their others.
