I can't believe i got excited to read this trash.

Story(3.5/10): I never thought a Tsugumi Ohba story, would remind me so much of all of the super cringy, gorefilled edgy manga, that were funnily enough inspired by Death Note, it's like Akira Toriyama writing the FanFic plot for Dragon Ball Super.
There was no real meaningful development aside of the first few chapters, no new powers, no new rules, no interesting new concept or even any event that would give any motivation whatsoever to the main character, or maybe make we see him in a different light, the story grew stale even before the end of the first volume, the story could've been 30 chapters and it wouldn't lose anything, it might as well have ended after the first main villain is defeated halfway through and it would've been better for it, but not by much.

Art(8.5/10): Takeshi Obata delivers, as always, been a fan of him since the Hikaru no Go days, even though this is not his best, Platinum End is nothing to sniff at even with a couple of bland designs, specially the "battle suits", i also expected a bit more detail in the artwork, since this is a monthly title.

Characters(2/10): I don't understand what happened, every characters needs to be hyper over the top or as dull as a rock.
After a certain point in Ohba's career he stopped being able to write believable people, and he couldn't give even a little personality to Platinum End's main character if his life depended on it, don't even bring up female characters and the romance, they're as shallow as the respect Light has to his mother, sister and Misa.

Enjoyment(3/10): Was there really any, aside of seeing Obata's work, i wish he would find a better writer to work with.

Conclusion:
This is not the Death Note successor you were hoping for, it may be a blunder from a successful writer, you can see all of the worse aspects of Ohba's writing style, how convoluted the story can get, so much exposition and bs philosophy that leads nowhere.

The ridiculous ending made me chuckle, overall score of 3.5/10 it is.
