It's neither. Herzog doesn't make a hero of the whacky Treadwell. Nor does he impale him. It's realistic, and there's no "snuff" whatsoever. Nothing.
I don't know why you put quotes around "documentary", because that's what it is. That's Herzog's specialty.
You guys need to separate the message from the messenger. Herzog is one of the great filmmakers of the 20th century.
Which is what, in your opinion? Like I said, I haven't seen the Herzog flick -- but I know what Treadwell did.
He really did do an outstanding job. And his commentary on film making was interesting.
In fact he made the point I came to believe. Treadwell was whatever he was, but the film he took is either enjoyable, fascinating, or just incredible to see.
