I think you're spot on Nigel in articulating how these characters may not all be likeable but they are interesting. To piggyback on your Clint Eastwood character opinion it's important to note how we learn William Munny is a bad dude. Through prologue text and dialogue from "The Scholfield Kid" and Ned we learn of Munny's horrific past but the actions we see of him from the opening portray a loving father trying to do the right thing by his two children and late wife. There is a terrific internal conflict established by his duality within the first 10 minutes of the film which I consider to be the best western ever made.
How is $90 free? Maybe he means the first video of the course. Thousands sign up, Herzog takes his cut and makes a documentary against capitalism and the internet, got it.
