The opening scene of the first novel during the cultural revolution I recall as being absolutely fantastic. The rest of that novel was a big rather dull Asimovian deus ex, and then the rest of the series was more of that.

Big disappointment, very much not what I think of as hard sci-fi which is what it often gets billed as, and I absolutely do not get the love for it here.

Don't get me wrong, there's some total dross out there that I adore, but this ain't it for me.
