Dunno about the movie, but the book is quite neutral about the nature of the totalitarian government. All it is interested in is maintaining its power over the oppressed. As portrayed, it is very easy for readers/viewers to project whatever group they want upon the characters depicted: if you want to see the future of the Obama, so President Snow is; if you want that evil to be Bush and the Republicans, that’s what you’ll see; if you want your favored group depicted as evil by the author/director so you can demonize the latter, so be it.
Insofar as politics go, this story is a Roarshach test. You’ll see what you want there, and I’ve seen a lot of people want a broad spectrum.
You should watch the movie and get back. It has a pretty obvious agenda to me, and frankly I’d be surprised if the book doesn’t as well (but I haven’t read it). If the book had anything like a conservative message, I doubt the leftist American Library Association would be recommending it.
