Goblin Slayer

Goblin Slayer is a Dark-fantasy Light Novel series with a manga and then anime adaptation created by Kumo Kagyu, following the adventures of the titular Goblin Slayer on his quest to destroy the evil race of Goblins.

Plot
A young Priestess signs up with the Adventurers' Guild in order to help others. Among the many contracts available, Goblin slaying is one of the most common, yet lowest paying jobs available, leading others to believe it's for rookie adventurers. After a disastrous Goblin-slaying contract with other rookie adventurers, the Priestess meets the mysterious Goblin Slayer, a man who seems purely focused on the eradication of Goblins.

Bad Qualities

 * 1) The characters get little to no development in the story. They literally do not even have any names besides the super-generic professions they possess which is lazy.
 * 2) Goblin Slayer is just that, he does not have a single other personality trait besides being an utter Gary Stu and hating goblins. Not to mention that he's also super preachy, trying too hard to make his own backstory seem "so tragic and unbearable", yet said backstory is about as cliché as they come with no depth whatsoever. Literally the characters in the first part, most of whom are killed off early, have much more depth than him.
 * 3) They literally say that Goblins are the least threatening of the creatures in that world, which just makes it sound boring. What's worse is that they tease the appearance of much more unique and actually cool creatures, yet never even show them. What also makes no sense is how goblins would be able to threaten an entire country when they're mostly in caves.
 * 4) Constant rape scenes. In comparison with Dynamite Entertainment's Crossed from comic writer Garth Ennis, the Goblins try to rape literally every female character that comes their way, which only serves to reinforce the "damsel in distress" stereotype. Not to mention that MOST OF THOSE GIRLS ARE MINORS, which is even more messed up.
 * 5) LOADS OF EXPOSITION. While that's a problem with a lot of manga series, this one is especially bad because it does nothing to further the story, gets WAY too preachy, and utterly kills the momentum of the story.
 * 6) The series feels like it's trying way too hard to emulate the manga, Berserk with more edginess and violence, only Berserk knew when to show restraint and has a well-developed story and characters to go along with it, whereas Goblin Slayer feels like it's focusing even too much on the edginess and not enough on anything else.
 * 7) Things feel way too planned out on Goblin Slayer's part to feel even remotely believable that he wins. It's clear he only wins because the plot needs him to, as opposed to the aforementioned Berserk, where the main character doesn't always win, and in fact often takes a beating first.
 * 8) Lots of IDIOT MOVES:
 * 9) Warrior swings his sword towards the goblins. But, his sword hit the side of the cave and when it fell out of his hand, Warrior was swarmed and beaten to death by goblins.
 * 10) Fighter attempted to kick the hobgoblin, but it just grabbed her foot as the goblins torture her.

Good Qualities

 * 1) At least plenty of the characters in the world are decent people, which makes the series avoid feeling exploitative or mean-spirited, unlike Crossed.
 * 2) Some likeable characters like the Priestess who gets some visible development as time goes on.
 * 3) It has some realistic elements such as armor and weapons not always working in certain situations and degrading overtime.
 * 4) At least it kind of has a message against rape, as the Goblins are quite clearly the real villains of the story.
 * 5) Good art style.
 * 6) It shows restraint with it's imagery, choosing not to show rape very graphically (even if it's clear what's happening) and have particularly violent moments, especially against children, not be shown explicitly.
 * 7) It could be enjoyable to those looking for less of a story and a more simple fantasy outing.
 * 8) The first chapter uses some actually interesting storytelling devices, like showing the hot-headed one be inspired by a story of an adventurer surviving miraculously thanks to help from his long time friends. That flashback is contrasted with the hot-headed adventurer being killed by goblins in the present day, which adds a tragic twist to what was expected. This is also used for the other adventurers, showing their lives of training and success being reduced to nothing in a single moment as they're overrun by goblins.
