(This review contains mild spoilers)
I'll keep it short and focus on the second half as I already spent my energy on the anime adaptation which follows the manga strictly.

Pros:
● Very good foreshadowing for the first half
● Amazing worldbuilding, future punk + magic, why not!
● Nice tiddies, I approve them.
● I really liked Nikaido's skill description, it puts alot of weight behind her actions.

Cons:
● After first half, plot feels patched up, made on the go.
● The idea for the creation of the final boss is a bit too cliche, embodiment of feelings strikes... yet again...
● Final arc dragged for too long and it ended with an anticlimactic boss fight. Ass-pull Gyoza Wand had to be summoned! Someone dropped the ball seriously..
● Second half (aka final arc) was too action heavy till very end, I think overall character development suffered there a bit. There was just not enough room for feelings, it remained intense for dozens of chapters.
● Kaiman's past took alot more episodes than present Kaiman's development. When Nikaido behaves affectionate towards him, it just looks unreasonable because Nikaido literally spent more time with many other characters.
● Epilogue wasn't satisfying enough. It was one solid slice of life chapter but since the cast is too large alot remained unanswered.. Some side characters feel unfinished/unpolished despite their common appearence Dokuka, Tetsujo, Kasukabe, Kawajiri. I feel like they all had to say a couple more lines...
● The author teased the romance between Kaiman & Nikaido, Shin & Noi, Haru & Haze, Ebisu & Fuji many times but never developed it. I know forming couples is common trope, therefore authors are avoiding it these days but after many crucial events how do they even maintain their "friendzoneship" ? Honestly at some point they just behave like robots..This one is maybe too personal but my eyes searched for some more sparkles!

Overall, I am blown away by Dorohedoro. After anime ended with cliffhanger, I dipped all the 190 chapters, 18 years of work in 3 or 4 days. No regrets! It was a unique experience for me because I have never read a "gory" manga written by a female author before. It didnt leave a strong and dramatic aftertaste. Story is gory and a bit silly after all... I couldn't help myself but notice the drastic improvement in artwork after volume 3, and it got even better gradually. Problems here & there but I got hooked up in the end..
