EDIT: Review has been updated after finishing the audiobook.
That was truly a disappointment.
Aside from the truly magnificient work Graphic Audio has done on the audiobook, everything else about the story has gone downhill significantly.
Parroting another reviewer's phrase "If I'm reading a story about an overpowered character is because I want to see an overpowered character", and that's exactly what Seth Ring keeps not delivering on.
At every single point he finding increasingly contrived reasons to limit or restrict the MC and for the MC to constantly keep dropping the idiot ball to make for believable adversaries, and in this book this got to an excessive level, with John's decision not to kill the bad guy and then seal his own power away.
It made no sense, it wasn't properly built up, and overall it reeked of the author's inability to deliver on the "Promise" (as Sanderson calls it) done to the readers.
Now, the continuation of that storyline ended up providing an understandable conclusion, and the few scenes where John has the chance to learn things about himself that he wouldn't have been able without having his powers stripped were interesting, but overall the contrived plot reasons for all the scenes of him being beat down and then entrapped were disappointing and unsatisfying
I'm really sad about this, because I loved the premise, I loved the worldbuilding, and loved the initial characterization (though afterwards John's behavior became so inconsistent that the characterization itself was broken). And I loved the fact that Graphic Audio picked up a Litrpg for adaptation.
I'm a bit invested still so I'll wait for the next Graphic Audio audiobook, but definitely not enough to pick up the normal audiobook or the ebook to continue.
