Where I disagree with your article is your letting Jackson off the hook. The Hobbit, like King Kong, like the LOTR trilogy are not the product of corporate film making, whether they foot the bill or not. There is no influence, no choice, no direction that isn't pure Jackson. His supervisors, producers, etc. are figure heads even. He's making the films he wanted to make the way he wanted to make them. Like Lucas. Like Cameron.
With this in mind the problems with the action sequences and animated hordes are not the result of any deficiency in the armies of people it took to create them. Or have we all forgotten all the boring, repetitive chase sequences in King Kong. 110% of this is Peter Jackson. Just like the self-mutilation of the Star Wars saga by Lucas, this is an "auteur" with total control, no limits and no one telling them "no."
The artists that worked night and day, more often than not seven days a week, for months (or years, in the case of Cameron and Avatar) on end, are execution. They're doing their job, often at the expense of their own health, their families and any regard for anything other than the film. In the case of filmmakers like Peter Jackson and James Cameron or George Lucas there's also the masochistic reality of these people pushing themselves even further, allowing themselves to be exploited even more than usual, due to their futile idol worship.
I used to be one of them.
These filmmakers learned from the mistake of Francis Ford Copolla who was only compelled to return from the Philipines and eventually complete Apocalypse Now with the threat of the destruction of the negative he'd already shot. With these guys, there is no outside influence, no tampering, no limits and like Kurtz going off into Cambodia, no method, only madness.
edit: re-reading several posts I've made on this subject I'm gonna try to make this one my last. I just hate the negativity it brings out of me. You'd think I was talking about the GOP or whalers, lol. I'm gonna try to concentrate on positive stuff and enjoy the anamorphic discussions which was what brought me to this forum in the first place.
