Just finished
The Dark Forest and have the final book of the trilogy on reserve, but it will probably be a few months until it is available.
I liked it better than
The Three Body Problem - like
@Capt. Factorial said, the first book essentially just sets up what follows and this story is definitely more interesting and entertaining. The first half of
The Dark Forest is still too long/tedious though, at least for my tastes. Get to the point, man! You don't need to spend 10 pages on what can be covered in 2.
Also, I still find some of his writing/plot points a bit obtuse or strange, but maybe more of this will pull together in the final book? His writing is definitely unique in my experience and I enjoy it for the strange ideas he comes up with, if nothing else.
