Just saw it. I think the Coen brothers have to have a real love for that golden age of Hollywood to make fun of it the way they do. It's a tribute to the craft that went into all the old dance numbers, miniature special effects, Busby Berkeley swimming scenes and epic film making while poking fun at them all. Really great stuff. Just like all their films, I'm going to have to rewatch it a few times to get all the layers.
