Time Out saysJohn Nada (Piper) is grouchy because ever since he arrived in Los Angeles from Colorado, there's been nothing but trouble. People are rude, he lives on a campsite, and then the place is demolished by the cops. Things get worse when he happens across a hidden stash of special sunglasses. Donning a pair, his vision is literally reduced to black-and-white, revealing a terrible plot being perpetrated on the underclass. Skeletal aliens have invaded earth, taking on human guise, hogging the best jobs, and placing subliminal messages on hoardings and magazines which instruct the man on the street to 'Obey', 'Submit', 'Marry and Reproduce'. It's sunglasses for all as Nada and his pal Frank (David) attempt to infiltrate the media and expose the conspiracy. The black-and-white visuals disturb for only so long, and while themes of indoctrination and conspiracy prove initially intriguing, the film quickly descends into fistfights and gunfire. Still, there's little about the comic strip action to suggest that we should be taking this too seriously.
