So why no remake?

This question really baffels me. It was low-budget cult hit, who cares what it did at the box office.

Aspects of the story are right on point with today's society. A disappearing middle class, a sense that the media is controlling us, smart phone addiction (shown in the movie as tv addiction), trust in the government, a reported lack empathy for our fellow man.

This movie could also be viewed as anti-wealth, anti-capitalist, even anti-semitic.. Perhaps because decision makers in Hollywood are already well off, they don't want to help further ignite a class war.

Also, it could stir up/increase the number of crazies out there who's world view is shall we say, 'unique'.
