I really wanted to like They Live especially after having watched The Pervert's Guide to Cinema. Similar with The Thing which is also directed by John Carpenter. Both movies start really strong and then just descend into pointless violence. Anyway, I digress ...
Nada is not smart. He's a useful idiot. I think that like The Thing, They Live is pretty ideological and subversive, but it's also just a weird campy movie. It's a genre flick, but there's a reason it's a cult classic. Just like Zizek and his guide to cinema, Carpenter knows how to make iconic quotable expressions involving a camera.

So it goes.
Artists tell the truth by first telling a lie.
