Yes I agree with you whole heartedly. But I am trying to play devils advocate here, and come up with some reasons why people might not like this film, regardless of whether you and I agree with those reasons or not.
Although Nero looks like a hippie, I don't think this really detracts from the film. I did find it a little bit preachy however, it seemed they were trying too hard to "send a message".
But I do think its a great film. Not just great for a SW, great for a Western period.
