It can easily be said that this third arc is the best so far since it brings development of a new abyss layer through a less passive way. This season also introduces characters who have their importance and charisma. I really didn't regret reading Manga since it is the first time I'm both reading and watching a Series which draw so much attention from audiance. From a manga reader perspective, Made in Abyss can get even better in its anime journey. There is a thing that I didn't like a lot which was CGI applied to some characters. However it's kind of acceptable since it add a tone of mischievous and mistery.
There are still amazing soundtracks combined to epic horror scenes, good pacing and easy show to enjoy for most of the public. People usually don't regret to watch, it is a good choice and you can like it.
If you have never ever watched Made in Abyss, it also would be cool to watch its movies instead Series. That's why they are almost the same than all episodes but packed together in a easier way to watch.
