What Are The Minimums To Hype Without Lying?

I was watching TV yesterday, and a Spiderman 3 commercial came on.

The voiceover happily intoned "Critics around the world agree that Spiderman 3 is easily the best of the trilogy."

So it made me wonder exactly what has to happen for a company to be able to make that statement in a way that even has a modicum of truth to it.

How many critics do you really need, to have "critics around the world"? Are we talking a guy in Des Moines, someone in India, a critic in France and maybe one in Japan? Do they even need four?

Can't I legitimately use this to hype my own work? If I know some people in a few other countries, and they like my script, can't I say that "readers around the world agree that Scott Mullen's HIDE is not only the best unproduced screenplay they have ever read, but the best thriller of the past 20 years?"

Stuff like this could work sexually, too. "Women around the U.S. agree that when it comes to love-making, Irwin Jones is certainly above-average, and he'll even buy you dinner".
