I think it is. The world-building and characters are well-developed. The plot keeps you engaged throughout. But it might not be for everyone, depending on your taste in manga.
Well, it could be that the manga has deep character development or explores themes in a thought-provoking way that makes blaming it unjustified. Maybe the issues people might have with it are more about personal preferences than actual flaws in the work itself.
In general, the Anonymous Noise anime is comparable to the manga. Some minor details might be different, but the core elements and themes remain intact. There are also visual and audio enhancements in the anime that add to the experience.
