Not great, not awful. There are a few funny touches but the story flowed like watery syrup (not exactly a good thing.) Just long enough to prevent its welcome being worn out. Eastwood's Eastwood but Duvall was a little disappointing.
It was ok, but I can see why Eastwood started directing his own westerns after this one as it lacked that certain intangible that makes all Eastwood directed westerns special. That of course being interesting shit.
