I'm maybe about three quarters of the way through The Dark Forrest at the moment. It's good, but not as good as The Three Body Problem. I'm definitely finding it a bit more of a slog in places, whereas I couldn't put the first one down. The characters are just not as compelling. Obviously it's basically a totally new cast, so it feels a bit of a re-set in that respect.
Although his ability to come up with really interesting ideas and concepts is still off the chart.

The whole concept of a "Wallfacer" is great. Just somebody working with complete autonomy to try and save the world. Although I've just got to the bit where he (Luo Ji) wakes up in the future and they've binned the whole project off. I'm certain he will still have a role to play though.
The best character was the South American lad who's plan was to bomb Mercury to shit so it gets sucked into the sun, triggering some sort of extinction level event that ends everything. Basically some dead mans switch style situation where if the aliens come near he goes "scorched earth" but on the entire solar system.
Unfortunately he got found out and stoned to death for his ideas.
