3 Body Problem is a must watch.
I agree; it starts slow, but improves as it goes.
For those who did not read the book, some plot directions might be a little "weird".
I don't know the book, but books are usually (almost) error-free, while there are so many errors in filmed versions. I don't mean not following the story tightly, but for example an actor carrying a watch in an ancient movie (just for example). Those do stick out a lot for me, most of the times i just notice them, but sometimes i find them really annoying. Overall, the error-rate was ok-ish when following "3 Body Problem".
However, the series was really good, i enjoyed watching it a lot, just finished it two days ago. Had to watch the scence where the ship was fucked over three times in a row
