Jennie and I saw this last night. I thought it was fantastic, though I could have done without the song at the very end that Eastwood sang.
Clint Eastwood's character is like the world's biggest asshole. It's a very serious movie overall but has a ton of lighthearted, humorous moments. In a lot of ways it's like Million Dollar Baby in the sense that the pacing, cameras, and way they do the dialog are very close.
