I find the Coen brothers very hit or miss, but I love that they are out there. Miller's Crossing is among my top five favorite films of all time. I am one of the few folks who was bored by Fargo, and I actually stopped watching The Ladykillers half way through. But I love O Brother, Where Art Thou? enough to put it in a Top 20 list.
So while I don't love every Coen brothers' film, I love that they are out there, pushing the envelope, making such unique offerings. Everything they do is worth seeing, even when it doesn't work for me personally, and at least one of their films is among my favorite films of all. So I'm pretty excited to learn they're going to be doing Michael Chabon's The Yiddish Policemen's Union as their film-after-next.
