=Art=
Artstyle and character design are generic, forgettable at worst.
The only notable thing I like is a specific Orc's tanky armor much later in the story. It looked kinda cool~
=Characters=
I don't care for them because they're either:
- Rimuru fanatics
- friends/allies
- future friends/fanatics, before they get their asses handed to them
- some evil character to be killed off
Only two, maybe three characters have grown. The rest remain static, especially Rimuru fanatics.
The MC is the most uninteresting of them all, as detailed below.
=Story=
"Weak" slime is actually god-like sums it up pretty well.
You've got all the typical bad traits of isekai trash:
- dead MC reincarnated into another world
- MC gets OP skills for no reason
- Powerup through eating
- MC breezes through all the problems that he encounters, no sweat!
I don't have a problem with reincarnation, but the rest...
==MC gets OP skills==
Getting all these skills through no effort, or just "randomly" by doing simple stuff isn't impressive at all. If not by chance, miraculously, he'll get a powerup that'll let him demolish his opponents, or get a resistance skill that makes him immune to stuff during a fight, or later in the story. No struggle equals no interesting story!
Not only is he the most powerful, but he also has a ton of skills! My eyes just glaze over whenever he suddenly learns a bunch of skills. No one's gonna bother remembering all of that anyway, at least until he pulls it out of his slimey ass later.
I wouldn't complain about this if there are limits to their abilities and/or if they struggled and took a long time to attain their power, but the problem is they usually have no limits nor a price to his powers whatsoever. Even if he was an absolute saint in his past life and he deserved being OP, it would still not make for an interesting story without the struggle.
Since it's part of his skill, let's also talk about the Great Sage. I loathe her existence. She's an exposition fairy that violates "show, don't tell", and most of his OP-ness is caused by her. Rimuru would be struggling a whole lot more and wouldn't have done some things if she didn't exist, but he would've been a better character as a result.
==Powerup through eating==
One of the most basic actions for survival apparently makes you OP as heck. If this isn't an indication of lazy writing next to becoming OP just because of existing, I don't know what is!
If it took a while to learn and get better at his skills, then great. The problem is he'll quickly if not instantly master them, and apparently, not even a friggin dragon is immune to his eating skill. All of this would make some sort of sense if he was a glutton in his past life, but he wasn't even that.
==MC breezes through all the problems that he encounters, no sweat!==
No stakes at all in this manga! He'll just learn a skill later that will win him the battle/war easily! But enough about him being OP combat-wise, what about other stuff?
Met a powerful character that could've killed him or destroyed his village? We're just friends, nothing to worry about!
Lording over a village, and later a country? Easy-peasy! It's not like a forest in a fantasy world is that dangerous!
Winning a war, and incorporating the losing side to his village/country? No bad blood nor food shortage problems whatsoever!
Some character being a jerk to Rimuru, or rightfully being cautious of such a god-like being? Eh, they'll worship the very air he breathes later!
Other powerful countries? 100% trust the god-like slime, and we're also friends! Enemy countries just get steamrolled.
That one horrible thing that happened that could've made the whole manga a lot more interesting? Lol, let's just literally rewrite the laws of reality and undo all that! Might as well make the MC and everyone in the country stronger too!
Let's summon some powerful demons, what could possibly go wrong? The answer is: nothing, because they're all absolutely obedient to him!
Problems are the spice that makes stories interesting, but there are no problems that he can't solve easily and swiftly.
=Enjoyment=
I'm aware life is hard, but how can people root for someone that has everything handed to them? I did not enjoy reading this, and I'm merely reading this to get better as a writer cause you gotta read garbage too to avoid making the same mistakes. I would give this a 1, but I'm saving that for absolutely horrendous things.
