Its not anti comunist. Its politics are not coherent so it may somtimes seem a bit lib. From what i remember of the first book the author likes china as it is now and thinks there should be more funding for basic science. Wich i agree with. So its not bad. But dosent have any belefs besides that.
The phisics is almost completly wrong tho.
Someone else pointed out it is very popular with the current chinise intelligentsia. Wich makes sense because it somewhat flaters that type of person. The parts about the cultural revolution seem to be due to that pandering. But i did not think it was really malicious.
I liked it, not enough to read the seqiels tho. In my case it was the phisics being wrong that made it seem cheap. It felt in some parts like the cops personality that the aithor was trying too hard to be a campbellian. At least the campbellians were scientists and engeneeres.
