Granted for my summaries that's somewhat because I used nicknames for new characters. But largely it comes down to there is just nothing interesting happening. Every month the chapter does not leave one eager for the next chapter. It is just constantly spinning its wheels. Even if one was interested eventually they will be worn down by the tedium.
Bleach is able to bounce back due to a great adaptation of a decent arc. Even if they tried to do that same for this...I want to say it won't work, but some people will just watch anything.
What I mean is, usually sequel or continiation of same universe goes in one of two directions:
- Direct sequel, that uses same logic and in-universe laws of things/powers/characters, maybe with some slight additions, so reader can mostly jump back in and don't feel lost.
- Stand alone continuation, new cast, new logic of how things operate with minor drops or references to original work, so if new reader is in - they don't need to buy 60 volumes of previous work to know plotlines or why things happening in this story.
Granted, in manga 2nd type of story is rather rare, but it does happend, most recent one is Fire Brigade. With Naruto/Burito situation, 70 volumes of original story, where one of main themes was Naruto trying to change system and break cycle that caused suffering and wars, so logical question would be, what is sequel about? If main character of original story succeeded - does sequel changes genre? No, its still a battle shonen, does that mean main character on original work dies, and just passes torch to next generation? No, he's alive... just not main character anymore? Even more so, now its not a story about ninjas, now there is cybors, aliens, clones (yes, they were in original too, but it was deus ex machina even there).
So all in all, while changing from ninja-magic theme to some proto-sci-fi, inventing some bland new cast, while dragging old cast throught the mud, this manga doesn't really land any idenity on itself. Granted thats an observation of person that never read any chapter, only from description and reviews of chapters in here or elsewhere.
