Isn't this pretty much every Eastwood directed film? That's neither praise nor criticism from me, just how I see them.
I think it was one of the problems here though, a lot of elements were added in the second half in order to give the story a more straightforward narrative that would make sense to casual viewers, such as giving us a villain. It felt like a movie that was stronger as an idea than actually a cinematic story, but I found it very interesting and well made at the least, even though I'm not sure what to think about the real man.
