I found the whole series fascinating; definitely comes from unique angles in my opinion/experience. Really got me thinking about things I hadn't considered, and with different perspectives and nuance than I would likely ever arrive at on my own. I feel like the series is worth reading in its entirety, but I can also commiserate with losing interest or even feeling too fatigued to bother finishing. (Also, there was a weird part dealing with gender that felt almost like a non sequitur; I found it jarring and necessary, but I'm also not out here any literary awards.) What language are you reading it in? If it's English, it might be worth noting The Dark Forest has a different translator than the other two.

The Dark Forest is really dark. I struggle with the topic of death and I had a really hard time emotionally with it. Managed to get to the end but I don't know if I need to read it again, also in contrast to the first two books.
