"They Live!"
A classic of the cinamatic arts. No doubt about it, it will down in history with Citizen Kane, The Birth Of A Nation, The Wild Bunch, Apocalypse Now, and The Incredibly Strange Creatures Who Stopped Living and Became Mixed-Up Zombies.
Actually, those are important movies. Whatever that original zombie flick was (Day of the Dead?) and all of the sequels, Freddie, Friday 13, slasher stuff, I find obnoxious, rather sad, depressing, but important. Popular culture, hey, the bedrock of Democracy.
Anyway, liked "They Live". If you want a movie that has caused real damage to Western Civilization, try Jackson's "Lord of the Ring" cycle.
LOL! I sorta liked it, they had a good idea just didn't pull it off well.
