I basically agree with this. I see all of its virtues, and I think there's something to be said for it as the first movie that truly crystallizes what people recognize as the "Coen style." But there are several Coen comedies I enjoy more. It's a purely subjective thing.
If it were up to me, I'd probably send like 15 Coen Brothers movies into space.
Since it's not, this isn't my choice to do so, even though I recognize it's greatness. (I currently place it as the 11th-best Coen film.)
