For nastiness, though, Pleasantville is far outstripped by the contemporary Arlington Road, which is just vile and slanders straight, conservative America as a bunch of car-bombers. Tim Robbins has done a number of portrayals like this, and rivals Gary Oldman (The Contender, JFK) as an enthusiastic portrayer of bad guys generally, but never with more relish than when they are played as "conservatives" or authority figures (The Player).
And no mention of comrade Oliver Stone? The all-time champ for psychotic liberal lunacy HAS to be "JFK". Nothing else is close. Except for his "Salvador","Talk Radio", "Wall Street", "Nixon", "Born on the Fourth of July","Natural Born Killers". And his next movie is about Castro. Can't wait.
Basically, what the filmmakers were doing was attributing to Robbins character all the traits that other paranoia films had ascribed to agents of other governments or our own. And that transfer wasn't very well done. You could see just how flimsy and contrived it was, and how crudely it fit together.
What Hollywood does is to take the hostility and fear that "outsiders" produce in cultures and societies and direct it against "insiders," or "people like us." Unfortunately this is done with all the crudeness that earlier societies brought to their fear of outsiders. It's combined with some technical cleverness, but you can see that it's just an attempt to turn old folktales into political propaganda.
