I found the book entirely reasonable and timely. You have people who don't trust the government, factions within those, and worldwide secret organizations dedicated to keeping the status quo. You have scientists caught up in the middle, eco terrorists and nihilists.. There is even a rough around the edges detective working the case... Its got a lot in it for everyone. That the aliens use a game as a recruiting tool was well done as well. I enjoyed the fictitious planet of the aliens in 3body and thought that the whole dehydration and time dilation thing was clever and that their world in general was novel.
The plot is plausible, very much so after the last few years where we have seen so many fighting against their own best interests. The way the aliens spy on humanity is also quite good and reminds me of vernor vinges localizer technology.
So i really did enjoy the book and recomend it to others, who also enjoy it. So to each their own. I dont know if i will watch this video of it, because books always contain more than a video can express so i am almost always disapointed. But it would lend itself really well to movies or series for sure. maybe 32 hours would be enough to do it. There are some big concepts explored, especially about ones place in the universe.
