I have only read "Three-Body Problem", and I found it to be atrocious writing on pretty much all levels. Language-wise, it was more cliched and wooden than many fanfics I've read. Character development is non-existent, and most of the characters are very shallow and only exist to advance the plot. The plot itself, aside from the basic idea of a three-body system with life, was also very boring - the only part of it that I actually looked forward to continue reading was the Cultural Revolution flashbacks. And then there's the whole sci-fi part of it, which was beyond ridiculous - sentient elementary particles etc.
I still don't understand how that book gets so many good reviews, and especially don't understand people comparing it with Heinlein. Those reviews were the only reason why I forced myself to read it all the way through, and it still feels like some elaborate hoax, or accidentally ending up in some postmodernist art convention by mistake.
