Just watched it - what a film.... Utterly utterly impressed. Probably one of the best I've seen for a long time!
Clint Eastwood was superb. He is, to me, one of the select few actors that have just got better and better with age. Him, Jon Voight, Al Pachino, Robert De Niro, Sean Connery, Morgan Freeman - all fantastic actors that have grown old gracefully and true masters of their craft.
His acting was superb, the delivery, his direction. The script and screenplay was expertly done, the supporting cast was actually very good IMO (the girl that played Sue - Ahney Her - I thought was really good, and played her character very well)
Very sad, very moving, very well executed...
