Very nice affirmative lines from a veteran enthusiast on 991 at
http://www.autoextremist.com/

cited:
It’s not just a better 911, it’s the best Porsche ever built.
It’s everything they know so far. And more.
Much, much more.

Very positive - but realistic - review from someone who seems to know what he's talking about.  Realistic in the sense that he:

*  acknowledges that some of the characteristics which made classic 911s such exceptional cars to drive are forever gone,

*  but welcomes the change because the 991 is an all-round better car and because "you can't stop progress".
