I read them, and also his "Supernova Era" and one of his short stories collection.
First of all, the books doesn't really express any pro-CCP view which is obviously a relief. Remember any and all of you who use Steam are using a software who once censored a Taiwanese game in order to comply with the demands of CCP trolls because the game dared to include a subtle joke about their dear leader... So you should not be afraid of reading Liu.
In fact most of Liu's work express a fascination for the idea of blending east and west. Lots of his most successful characters are Eurasian, and several times he wrote stories in which the Earth's future leader is half Western half Asian. Whether this is a genuine belief or not is another matter entirely. but this is what you will read when you read his books. It's not like he writes every Chinese as a hero and ever white person as a villain or anything. The first tome of the Three Body problems include a scathing critique of the Cultural Revolution but then again this is now accepted by Beijing.
The Three Body Problem, like most of his work, finds its appeal in the fact that it is inspired by very realistic science. I think they call it Hard Science Fiction in English. There are very eery, even poetic concepts that Liu gets out of extremely complicated scientific facts.
Liu works better when he does short stories. He was primarily a short story writer. Thus, his enormous "Three body" trilogy is better read as a collection of short stories. Especially the last tome, which reads like several ideas he had sewn together. Each chapter reads like a short story with the same character as she somehow goes forward in the future and explores entirely different worlds.
The most thrilling thing about his books and what makes me read them to the end is this gigantic scope, enormous scientifical concepts that take you through eons of time and seemingly endless distances. His characters are cold and emotionless for the most but then again a lot of SF is like this (I am not primarily a SF reader, my favourite authors are definitely not in that genre). I think this is what Obama meant in the often-repeated quote where he said "the scope of (Liu's books) was immense". They indeed make you think out of the box. And I will always have respect for someone who dares to use something unusual (in this case, very arduous scientific concepts) to create fiction and even, I insist, something very poetic more than often.
He is not a groundbreaking author, he is not the future of literature or even SF alone, he is not a good person but he is not a CCP agent either, but I can't deny I had a good time reading all his books in a row as it was sufficiently weird to make me think out of my usual safe zone and on occasion make me dream a bit. THere are a few quotes I related to and kept in a notebook where I collect quotes.
His "Supernova Era" was the weakest and his short stories are the best in my opinion.
