Zardoz Rating System (ZRS) works by adhering to a list of strict criteria. Basically I deem something very shitty, so shitty, that it is as bad as watching the movie Zardoz at least one time. Zardoz being the worst movie that was ever made, in this universe and in others. The movie transcends shittiness, and often rips holes in the time/space continuum, to make other things shitty.. and to leave piles of crap floating around the cosmos, inherently making other things crappy in it's wake.. of shit. I will try to give you some facts to help you with the rating system below, to better understand how to use the ZRS.
1) The Zardoz Rating System was deemed by a group of my peers to be very hard to watch. Having Sean Connery, nudity and guns do not make this movie easier to watch in any way. No human or animal should be forced to watch the movie. The soundtrack alone is known to cause blindness and impotence in one out of three men.
2) I have never met anyone who has watched Zardoz more than five times in their life. Obviously the people who edited the movie never watched it more than once, so the rating system can not go higher than five (5) Zardoz Heads, and no less than one (1) head. A rating of five heads is almost unspeakable, and could cause a shit-paradox, causing the end of the world, life and everything.
3) Sean Connery himself has been known to use this system to rate things in his everyday life. Like when has to wait in line for anything, he often has fleeting moments of Zardoz, and often compares life's worst moments to having to suffer through another filming of the flaming horse-shit career endingly bad movie that is Zardoz.
4) When selecting a Zardoz head to use for your rating, use the grainiest, shitty possible quality image possible to express how fucking shitty the movie, and whatever your rating, really is. Examples below.
