I thoroughly enjoyed that and read the book afterwards. The series is quite close to the book with a lot of the dialogue being almost identical.
I hear that Netflix is going to release a Three Body series this year, but it's going to be set in the U.S. which seems strange to me as the Chinese setting was an important part of the plot. Apparently Liu Cixin is on board with it, so I'm sure I'll give it a watch.
Edit: I thought Hewei Yu was great as Da Shi - very entertaining.
There is a ton of discussion on here about it, which is why I am not getting into the details in this post. You can find it by putting "three body problem ycombinator" into a search engine.
In short, you are far from alone - it's vastly overrated by one group and always advertised (more than ANY other book on here), and another group (including myself) thinks the characters are flat, the science is weak, and the overall "solution" in the book is far too contrived.
TBP itself is bad, agreed, but the other books in the trilogy are some of the best ever. Dark Forest in particular is amazing —- for me the actual moment the series takes flight is when the Wallfacer Project is introduced in DF.
