I watched this a few weeks back and although I enjoyed it for the most part I was left feeling a little disappointed by it. I thought Eastwood wasn't up to his normal high standard and the supporting cast were terribly lacking. The story/idea itself was interesting enough but I just thought the execution was a little run-of-the-mill, for want of a better word/phrase.
I can usually watch Eastwood films over and over, whether it's a film he's done or whether he's just an actor in the film but I doubt very much I'll watch this one again tbh.
I'd probably give it 5/10.
