Do I Hear Seven?

I just noticed that for their reviews Time Out NY uses the six-star system. What the fuck is that about? Ratings, at least any I've seen in my 35 years, are usually based on either the 4 or 5 star system. Maybe even 10, the roundest of numbers. There's something symmetrical about 4, and 5 is half of ten so that's also standard. But six? Little pretentious, isn't it? And I know it used to be five - who's the wizard that called a meeting to say "you know what, we need to kick this up to six stars"? What the fuck.
