It's far-fetched,
Societies like the one depicted, sans the drug requirement, do exist.
They'd need to remove all the beep martial arts and give it a decent budget, but it could be an excellent sci-fi movie.
It doesn't need to be remade. The budget was sufficient. We see twentieth century automobiles in the film, and yet it makes sense because stagnant manufacturing innovation is a characteristic of far left wing countries. What I didn't like was how it felt a little rushed toward the end perhaps rushed overall. It has protagonist wish-fulfillment elements, but that's kind of normal for a lot of films.

This didn't seem very leftist, btw. Supreme martial law, totalitarian government and the slaughter of those with different beliefs doesn't seem like a leftist agenda.
It's interesting that you saw that in the film, which probably tells volumes about yourself, I mean when has PETA or feminists called for the slaughter of pets or art or music or emotion?

No remake needed. This movie is perfect.
A bright light can hollow the deepest of nothingness.

There is no need for a remake. The original just needs to be better known.
It's that man again!!
