It's funny you should say this. I suggest looking at polls from the 30's, to see how people felt in and about Italy and Germany before World War II. You'll find their citizens were some of the happiest in the world. I guess that means fascism's cool, huh?
Alternatively, China's people may be satisfied with their government for the same reason the Russians are and the Germans/Italians were: the economy is hot, which makes it easy to be happy. Once that stops, as it inevitably will, I'm pretty sure the lack of freedoms and other repressive measures, combined with the lack of regard for Chinese citizens' health and safety in favor of a quick buck will lead to a radically different internal opinion.
As to the rest of the world, their opinion may be negative because China doesn't really respect human rights, is keeping repressive regimes afloat abroad, and is a major pollutor. Granted those qualities are not exclusive to them, but the other countries that act similarly are also pretty reviled.
As to the communist part, China pretty much abandoned that philosophy a decade ago. Capitalism is what they've embraced nowadays, and as Marx himself would have cheerfully told you communism and capitalism are not the same thing at all.
