I watched Netflix's 3 Body Problem over two days. It was definitely competent enough to be watchable, but the more I think back on it the less I like it. I haven't read the books, so it's hard to separate some of the flaws in the adaptation from flaws in the source material. Since it was adapted by the Game of Thrones team, it's probably safe to assume it was mostly the former.
One of my main criticisms is that it seemed to introduce a lot of different ideas but only very shallowly, which I am going to assume is book -> TV lossiness, but when you do that this aggressively I feel like it makes the whole thing seem like a messy pile of absurdity. Another issue is that it seems like this world-ending threat can only be solved by a small handful of people who just happen to all know each other already, though (paradoxically) several of them basically do nothing productive until the very end, as obvious set-ups for a sequel. The most egregious issue that I can probably safely blame on the book is the whole Panama Canal thing, which seems like an indulgent excuse to use a "neat" sci-fi concept, but is so over the top and absurd that it could only exist in (bad) fiction.
OK, rant over I guess. If you've read the book(s) let me know that you think.
