I saw Hail, Caesar.
I happen to think the Coens are a national treasure, but this one was just ok. It was incredibly rich in terms of ideas and visuals and the various set pieces poking fun at the different classic hollywood genres were impressive.
To me though, it didn't quite come together as a satisfying whole. The Big Lebowski is similar (but much better) in the way it had all these skew threads (bowling, nihilism, bumbling noir detective piece, pornography, etc...), but that movie hit it out of the park. Maybe it's not fair to compare this new movie to Lebowski, but it's just not as good. Also, Hail, Caesar! is a comedy, but I can't help wishing it was funnier.
