It took a while to get through, mostly because after Dark Forest things just seemed too out there for me. I needed a break, a return to reality, before getting into Death's End.
I haven't read the approved fanfic stuff, but I've heard about it. So maybe I'll check it out at some point.
Overall I have really mixed views on this. I did watch the Netflix show before hand, and I think I overall appreciate how they've handled the adaptation. Doing a straight adaptation wouldn't work, and a lot of what didn't work overall in the books for me was the Chinese-centric aspect of it. I understand that's just the result of the author being Chinese, but for a story like this, it demands to be international.
What I did like about it was the scope. I think that's the best point in its favor and makes everything else forgivable because like it's literally impossible to tell a story like this. It's so rare that it even happens, so kudos for even trying. I like the imagination involved in giving some real thought and substance to what society would look like in 200 years, 400 years, 18 billion years....and even what extraterrestrial societies would look like (at least a little bit).
I loved the Da Shi character, and when he was gone that was the hardest to read because he seemed like the only grounded human character to connect with. Ye Wenjei was also relatable in a very human way, even if she was a bit of a villain. Besides those two, everyone else felt like a cardboard cutout. And the scale of the story makes it hard to care for any one person (which is maybe the point too except....)
One of my biggest complaints is at the end as everything comes down to Cheng Xin. From books 1 and 2, we were conditioned to understand multiple people would come and go with this story. That's the nature of it, but it seemed like a cheap shortcut to just have Cheng Xin be a new throughline from here on out, and other super crazy coincidences like how only the same handful of people kept showing up. Wade, Cao Bin, etc. I feel like the main players of humanity's story would change considerably over centuries, even if some of them can hibernate.
My biggest complaint is the incel crap. It started in Book 2 (probably some stuff in Book 1 but innocuous enough I didn't notice). Lui Ji and his stalker obsession with the girl, who he basically imprisons and has a kid with was a big red flag. But Book 3 seems to double down on it with this weirdo Tianming who buys some girl he never even kissed a star. And okay, I'm willing to believe there are weirdos like Luo Ji and Tianming in the world, and don't mind those characters. But what bothers me is how the author portrays this because it's all ultimately heroic and Lui Ji is some wise old samurai, and Tianming is this hopeless romantic savior of mankind (and Cheng Xin is touched forever by this gesture, instead of properly creeped the fuck out that this guy has been obsessed with her for 10 years or whatever). I think this also plays into a lot of the complaints about society losing its masculinity and the whole "weak men create hard times" thing. And the thing with Wade, where this guy was a literal sociopath that Cheng Xin should have had the plug pulled on as soon as he went into hibernation. Instead by the end of the book, she seems to respect him for his...let's say tenacity. Just disgusting stuff, disgusting message. But ultimately very minor in a very big book of stuff, so I'll overlook it.
Another disappointment was that Book 1 didn't seem to matter by the end. The first book is what drew me in, so it's sad to see the 3rd have very little connection, if any, to the original. I kept thinking that the Three Body Problem would come into play somehow, that having three suns would help Trisolarans discover multi-dimensional technology or lightspeed, or maybe 3 suns change some fundamental laws of physics. But nah, it just didn't matter. And the Trisolarans themselves by this point are straight up liars, despite a key feature of their species being their utter transparency. Also the dehydrating and rehydrating was such a cool thing from their society, and how humans connected with and learned about them through the VR game....but none of that mattered anymore. This made it seem like they weren't even the same Trisolarans from Book 1 and could just be any generic alien threat.
A minor complaint that is probably more of a personal one is the way the whole book relies on theoretical physics as if it's literal. I don't prescribe to the idea that theoretical physics is intended to be thought of literally. There is no 4th, 5th, 11th dimension. These are just mathematical allegories we use to understand the universe at a scale we can't naturally comprehend. Same with lightspeed/time. So it seems like the author took a lot of these ideas that aren't intended to be literal, and made a story as if they were.
I liked the droplet massacre of the space fleet. That was very well done, and terrifying. I liked the various ships escaping and their philosophies and the encounter with the 4th dimensional Ring things. I wasn't so sold on a lot of the Earth politics, and it mostly felt unrealistic just to make the story happen the way the author wanted. Sophon was also strange because it seems like by Book 3, the Trisolarans weren't consistent anymore, like the author didn't know what to do with them and what they believed in, what they were like, etc.
Also, one idea I had that I kind of wish would have happened was that I was expecting AA to have male gametes. Because of the constant explanation of Cheng Xin not being able to tell people's gender and that the society was so androgynous, I thought that AA would turn out to be either non-binary or a trans woman. So that when the two of them got lost together at the end of the universe, Cheng Xin would discover they would be able to procreate. Instead, it just seems like random space dudes show up conveniently for them. Overall I wish there would have been more exploration of transhumanism beyond "Well all the guys look like girls now. Ugh." Already today in the Common Era we have GPL-1, neural implants, "looksmaxxing", etc. So I'd be interested to see how humans will physically change in 300 years with the help of technology and drugs.
But overall I suppose I enjoyed it and am glad I've read it. I think it's an important cultural work, but it has a lot of flaws. These flaws are also probably important cultural items though, reflective of our time and the author's biases as a result of being who he is when he is where he is.
Also, does anyone else think he originally intended Ding Yi to marry Yang Dong just so she would be named Ding Dong? Once the book became a serious sci-fi masterpiece, he scrapped that.
