Like the way you increase/decrease your security settings with a pop up blocker Netflix should allow viewers to increase their movie recommending algorithm up to video store clerk snobbery status...just like having The Simpson's Comic Book Guy in your ipad:
Mild Disgust Setting: "Really?" when you select a "guilty pleasure"
Belligerent Contempt Setting: "Did your mother drop you a lot as a small child? You idiot: if you watch this they'll think it's popular and make a sequel. Is that what you want? You want to ruin society because you have lousy taste?"
A Belligerent Anniversary Setting would be beneficial too: "Hey jerkoff one year ago today you watched that Kate Hudson movie and blamed it on breaking up with Stephanie. You ever think if you had better movie taste women wouldn't leave you?"
The Netflix algorithm it's too polite which makes it unhelpful for modern society.
