God Forgives has also some flaws, it is not a perfect film, none of Coliizzi's is. In the middle part, when T&B steal the gold and escape with it until they are caught again, the film loses its momentum, some scenes are comparatively weak and the ideas grow thin.
But there is also terribly good stuff in it. As is in the other Colizzis. Especially in Boot Hill.
I also see a lot of Leone in it, but he made the Leone ideas his own, created in the end his own style. And some of the most beautiful scenes in his film are definitely not Leone.
