You know what may be a positive thing? If you read things like Yelp or some Phoenix newspapers there are time's PB is lets say, less then embraced by area residents. Always baffled me why but that's another story and pizza never fails to draw strong opinions.
These haters may just very well love him now. 
I know, I don't get it. PB on Yelp only has a 4 star rating... 4 stars? For what hundreds consider to be the best pizza in the country (or beyond)? Just haters I guess.. Pissed that they have to wait 2-3 hours to get seated. There will always be those people who are nothing who think they are special and should be treated as such. Unfortunately it is only in their own minds.
The other factor is hype I guess. They have such high expectations (beyond reasonable) and then they don't feel Bianco delivered unless they got pure ambrosia (again, relative to their own minds/taste/opinion) on a plate. Probably part of the reason Varasano's is getting pissy reviews on Yelp also.
"In many ways the work of a critic is easy -- we risk very little, yet enjoy a position over those who offer up their
work and themselves to our judgement. We thrive on negative criticism, which is fun to write and to read. But the bitter truth we critics must face is that in the grand scheme of things, the average piece of junk is probably more meaningful than our criticism designating it so." - Anton Ego, Ratatouille
