This manga kind of reads like as if your ordinary, altogether unoriginal fantasy jRPG's goblins, the exact same brutish, stupid, green, stunted ugly things as in every jRPG everywhere, suddenly collectively went like, ”Hey guys, how about we started to wage war seriously?”
And the entire rest of the bright and shiny jRPG videogame land, with whom everything's always done in the proper way of levels and rankings and well-organized videogame challenges, completely missed the memo, and soon they were like ”Did you just stab me with a shiv smeared with your shit?! That's not proper!”
But one man, probably secretly half-goblin under his helmet (it really would explain everything), is quick on the uptake and swiftly begins his one-man slaughter crusade, mercilessly murdering every goblin he comes across. And mostly everyone else sees him as an obsessive psychopath, recoiling with horror at his methods... even though, given how the goblins in this setting maintain their one-note videogame Chaotic Evil personality from infancy, like programmed machines that can't even theoretically be redeemed, they should all cheer him on and instantly join in on his extermination quest. He only ever comes across as any kind of a badass, or remotely smart and ruthless, in comparison to his fellow men, who are pretty much all morons and wimps.
In short, the setting of Goblin Slayer doesn't make a lick of sense. It really feels like you took two entirely different worlds, polar opposites in terms of tone and history, neither one actually remotely developed or nuanced, and mashed them together in a haphazard and all-in-all very thoughtless manner. And you know, if it had done that, the story might actually have had something to go for: the ensuing chaos would have surely been entertaining to behold, and there would've been something interesting in seeing the happier and more generic jRPG world scramble and panic in their struggle to adapt. Have both worlds develop some nuance as they're so combined. But having everybody act like it always was this way, yet not following through with their attitudes and sensibilities, is just jarring and inane.
It wasn't the only opportunity the manga missed. I think the author was trying to bring a bit of the grit and brutality back to what's generally seen – in east and west alike – often as a fairly cheerful and lighthearted genre and game, wherein characters are bold and heroic pest contr warriors of justice, fighting evil goblins and dark lords and such. But it wasn't always so. Early in its history the game was about rather more amoral treasure hunters on careful dungeon crawls, playing it smart and never ever fighting fair. The goblins here have a lot in common with the idea of ”Tucker's Kobolds” of those early years – but the goblins also miss the point of that story, that the same sentiment should be added to the more powerful monsters as well. ”If kobolds can do this to a group of PCs from 6th to 12th level,” quoth the original tale, ”picture what a few orcs and some low-level NPCs could do to a 12th-16th level group, or a gang of mid-level NPCs and monsters to a group of up to 20th level.”
Now that I think about it, I would've loved to see some more old-school sensitibilities be brought in. Exploration, mapmaking, resource management, noticing sloping tunnels and secret doors, a bunch of weird puzzles and traps, light and dark and noise – and as for the monsters, sneaking past them where you can, negotiating where possible, taking sides with the various goblin factions to play them against one another, only getting into fights as a last resort and even then with a stacked deck. I would've been simply delighted if this bunch of moron adventurers at the beginning had immediately gotten lost in the dungeon, started to run out of food, stumbling into ancient traps, getting separated by trapdoors and secret doors, torchlight flickering and dying and shadows deepening... all of that without so much as a single goblin jumping at them. Then the Goblin Slayer could've entered the scene and schooled them about how they really should behave deep in the unknown dark. Alas.
I did stick with the manga for a couple more volumes, to see if it'd get any better, maybe actually bring up some of the stuff I myself brought up here. It wasn't a complete trainwreck, despite all I've said and all I hoped of it: the art is pretty good, for one, managing the right kind of atmosphere and making all the blood and death and molestation look about as awful as your generic anime style can manage. I also liked the characters, thought that they played off each other well for the most part, and the absolutely harrowing threats thrown at them every day did a lot to endear me to them and make me invested for their safety. I've gone on record saying that characters are what run the story, and Goblin Slayer has some of that at least, enough for a half-star all on its own.
But at the end of the day, it just didn't deliver. After the grimy and gruesome beginning, it largely devolves to the usual standards of manga and anime, the harems and fanservice and generic fantasy action, just with an above-average amount of horrible murder and rape thrown in-
Say, what is it with all the rape anyway? That seems to have gotten a fair amount of backlash at this story, people hating it and stuff, but I was mostly just weary of it. It's what always happens. If a story wants to establish itself a serious grimdark tone, it has to threaten its womenfolk with rape. It gets trite.
Why not have the goblins be like xenomorphs, implanting their eggs to everyone, woman and man alike? That would've been one original note at least.
