A shounen where they actually let their female characters have their own moment and not just some damsel in distress chara to emphasized on how strong their male characters, is immediately a 10 to me🫶🫶

Pretty Generic

by Sniberus

Rating: 7.5 / 10.0

I think this is for the people that want a quick read if they are bored and they just want to see some action. The plot itself is very simple and I think that there was not much depth nor backstory to the plot whatsoever. The characters are fine but once again are lacking in depth at times. The progression felt a bit straight as it felt like one really big arc past like chapter 20 all the way to the end. Overall, pretty mid ngl.

In the end, it was merely fine.

Being frank, it started out great. The issue is that it started to quickly lose steam in the final stretch. You end the series with the feeling that it needed like 5 more chapters for character interactions to actually tie it up.

It's not a bad series, but I can't rate it higher than 6/10, even though the first half was an easy 9/10.

disappointing

Started promising, I even thought it is a postomodern take on Kaiju. But soon enough you realize this is extremely boring, uninteresting and repetitive battle shounen.

Action-Shounen That Does NOT Deliver On Its Name

by flesh_labyrinths

Rating: 5.0 / 10.0

What is the first thing you think when you read "Kaijuu"? Probably Godzilla. And what is Godzilla? Massive, gargantuan monstrosity that wreaks havoc and utter destruction. And Kaijuu#8 never quite delivers that feeling of scale and mass, instead opting to go onto the regular shounen rails.

It started promising enough - with mc being part of kaijuu disposal team - and interesting concept that would've made for much better manga - but after the typical shounen "hybridization", the tropes start piling up and the story looses any initial energy it had. After 7 volumes there was simply nothing worth sticking around for - lackluster battles, large cast of characters devoid of any development, bland main plot. Worse yet, i've seen it all before in other series, done better.

To summarize - if you're looking for kaijuus - you won't find many of them here. If you're looking for your next action shounen series - this will definitely scratch that itch, at least for a time.

Good but...

As in itself it's good.
But when you read mangas for quite some time. This is too basic, boring and whatever.
Everything is preddictable and I can't be bother to read a long ass mid shonen when there are so many better shonen.

Strong start, quickly devolved into a slew of generic, predictable, and boring developments

The main good consistency about this is the inking, I really love the clean inking and the monster designs.

It had an unique cast and development going for it in the beginning but then 10-20 chapters in it became a snooze fest, I regret giving this series 70-80 chapters a chance before dropping it.

The author doesn't bother developing the characters past their initial state, the choreography sucks and is bland, just shoot shoot shoot dodge dodge dodge with no strategy and tension whatsoever even when there's a shit tons of "stakes" and environmental destruction. I think the biggest issue is its blandness if the reader read this type of series before---it's like eating white bread for breakfast, brunch, lunch, then supper. It'll get old REAL FAST.

Generic shounen huh...

....I rarely wrote in Baka since I have new place for writing review. I even delete some of my old review. But I think I'll write for some review again in here, including this title.
Someone said it's good at beginning at later become generic shounen. Well. I didn't really agree. I think it's very shounen from the beginning cough XD.

At the time first discovered this manga, I really like the kaiju side of main character. Like most, it's what attracted me.

It just too bad it didn't explained well. How long it will kept unexplained? Maybe because I'm a Parasyte reader, I hope the explanation come in an instant. Or least- not taking this long (as far as I read right now, which vol 7).

I like the pace of the story. There might be a plot that felt rough (for me), but overall the story rollin' and make the character able to shine bright. I guess I'm pretty easy to please reader.
And yes. The power of friendship is real. I remember the bitter taste from the Blue Exorcist that I drop. And thank gudnes this won't be likenthat. Hopefully no more shounen reminds me of that XD.
I actually can be fangirling with many characters in this manga including-- obviously the vice capt' XD.
Anyw.
Though I like it, I always prefer if some story end while still shine bright. Like Ajin. It doesn't take too many arc and loads of unbelievable volume to wrap the story.
I might someday edit this review based on the ending and progress.
....or maybe not because I'll write that on other place! Lol.

slow pace and art kind of putting me off

I have been a fan of the monster genre tbh (Claymore, Berserk, Gantz, Freezing I have all read to various degree) and actually I kinda agree with some other reviews here in that K8 popularity feels weird. As @Tremofx said, K8 is pretty generic in it's MC background. And progression is, in my humble opinion, slow. There's really not much you can get from a chapter (even when it is an action chapter) and it has also been a source of my frustration. Another point is less realistic art -while I'll let any reader judge to their own standard, personally I like when the monsters are more 'alive' looking.

Well it's not like it doesn't have a future. I feel the fact that MC transformed because of some germ infecting him is an interesting plot tool, in which we have yet to know whether the Kaijus are of divided faction or MC has actually some hidden background of whatever. However, I kind of feel it will just be another story for me.
