Another Hollywood (spaghetti) formula Western where homicidal maniacs abound.
Here, Clint plays a homicidal maniac who obviously comes back from the dead after being killed by three bad guys and betrayed by an entire town of people.
So, the first thing he does is murder the only three men who weren't part of that. Makes sense? Not if you're looking for credible motivation.
But credible motivation isn't a part of most of Eastwood's Westerns. Certainly not the spaghetti ones.
So, the rest of the movie is just sound and fury, signifying nothing, and don't try to make sense out of any of it. It's just another movie about homicidal maniacs being everywhere. If the West or East or anywhere was anything like this, there wouldn't be anyone left in one piece to keep a town going. They'd all either be dead or crippled.
But Eastwood loved to be in that sort of thing. A hundred years from now, he'll be remembered for many good Westerns like Hang Em High and Joe Kidd, and his Rawhid series, and Dirty Harry, because he played credible characters in those.
He doesn't do that here.
