eh - I wasn't the biggest fan of the series. I read and somewhat enjoyed three body problem, but the way that exposition was introduced with a VR video game was weird to me, and then he totally misrepresents the Alpha Centauri system. Alpha Centauri A/B are in a close binary and Proxima is so far out that there is still some discussion on if it's actually gravitationally bound to the system. It's a very stable stellar system and not at all like how it's depicted. I would've rather had the extrasolar system just be some unnamed trinary system rather than specifically saying it's A Cent but totally misrepresenting it. IMO it's on the level of depicting Australians as literally being upside down.

It kinda ruins the series as serious speculative work if they get well-known physics like that so wrong.

Also book two has a really weird start and I couldn't really get through his search for the perfect girl section before just putting the series down as a whole.
