Wow, did you even watch the ending? How on earth did it "smash" the experts opinion? The only thing that happened was that the TV show host (who, though fictional, would work for the "RICH RICH RICH corporations" you're so transfixed by) asked the expert why the effects were confined to the Northeast. If you'd paid attention earlier in the film, you'd have noticed that someone mentioned that the Northeast has far more nuclear power plants than the rest of the country. Nuclear power plants were also specifically (and blatantly) visible in the background of the plant nursery they visit.

Not only that, but the film ends with the same thing happening in France, which gets the overwhelming majority of its energy from nuclear power. THAT'S what's being tied together. None of your paranoid ranting about fascism and corporations has any bearing in the film. Re-read your posts...90% of them is rant, unrelated to the film and not based in anything it says. I've read your post twice, and can't find any mention of any evidence in the actual film to support your convoluted conclusions.

Not only that, but even your basic logic is at fault. You say that the movie doesn't pull everything together at the end and make its cause obvious, and you take this alone as proof that it must be hiding a more sinister message. That's what's known as a "non-sequitur." Nothing in the first premise implies the second. Night has a history of stopping short of definitive explanations in his films, most notably in Signs, which presents many theories as to what the Aliens wanted, but no actual answers. I suppose that's actually a subversive commentary on American foreign policy, too, right?

Sorry, but either start citing some actual evidence within the film or spare us your craziness.
