The acting was fabulous, of course. But I came away perplexed about numerous critics' claims that the film represented a Eastwood's repudiation of the whole "vigilante" thing as represented by Dirty Harry and the like. While the error of Jimmy's murder of Dave came as a blow to both Jimmy and Sean, when revealed as a mistake, it didn't cripple them. Rather, Jimmy's wife consoled Jimmy by telling him that he did what he, as a "king," had to do. And Sean wasn't going to add to the tragedy by bringing his old friend to justice. The person who was shattered, OTOH, was Dave's wife, Celeste. She committed the fatal sin of not being loyal to her husband, by voicing her deep fear that he'd killed Jimmy's daughter. Ultimately, the message wasn't so much that vigilantism is wrong, but rather that loyalties to family (and friends) ought never to be breached, for any reason.
