Me, too! I'm about 80% the way through the audio book. There are no real spoilers below.
I don't think any of them are mind blowing. I have very mixed reviews of the books. I know too much about physics and such, and the author gets basic stuff wrong all the time. But I do really like the philosophical and ethical discussions, especially in The Dark Forest. There's just too much meandering plot surrounding these discussions. The books are twice as long as they should be.
For instance, the author talks about the tidal forces of black holes and the top scientists in the book say "maybe the tidal forces were small because the black hole was so small". In reality, it's specifically small black holes that have the highest tidal forces. You would only fall cleanly into a supermassive black hole.
There were like 4 major physics "WTF?" moments in the first book, and a few in the second, too. I'm not talking about the totally off the wall things like the sophons. I mean the normal physics stuff. I just try to ignore them and enjoy the story, but the author writes a lot of self indulgent stuff. Like the whole Luo Ji thing of him being this perfect author who really understands characters and literally hallucinates their lives. It's like the author is trying to write himself into the book. And in Death's End with the fairy tale stories that just went on and on! Same kind of thing.
There's a book 4 of the series, I found out, but written by another author. I don't know if that's a good thing or a bad. 😄
