These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
If Valkyrie didn't ask Caelan to drink her blood, he may have never gotten that obsessive.
Valkyrie has become this in later books. Is she simply a brave, innocent and genuinely good-natured Woobie who wants to save everyone she cares about from her Superpowered Evil Side (and ask for nothing in return) and thus jokes around or snarks to distract herself, or an overconfident reckless spoiled little brat who believes in solving her problems by punching them and wants everything and sacrifice nothing, like wanting adventure and excitement with no concern for the danger she's putting herself and others in?
Did Argeddion really think the people he murdered didn't "count", or was he just trying to delude himself into believing he could still be an Actual Pacifist because the alternative was too horrible for him?
Is the reflection just a mindless psychopath who killed Carol to gain power, or is she a pragmatic (she is Valkyrie's reflection, after all) human being who only wants the Sceptre to protect her family and her place in it?
Carol had grown up enough to realise how unpleasant she had been. She had awful self esteem issues... enough to warrant Jerkass Woobie status. And then, just when she's starting to learn magic and get a little more development, she's stabbed by Valkyrie's reflection.
There are some Randian/Objectivist themes, though they're somewhat more subtle.
Landy obviously thinks that the relationship between Bella and Edward in Twilight is dangerous and unhealthy and viciously satirises it.
Or maybe he just finds it absolutely ridiculous.Or dangerous and unhealthy and ridiculous.
Base Breaker: Opinion is strongly divided on The Last Stand Of Dead Men; some reckon it is the best instalment yet, while others are writing death threats to the author. (He expected it.) Those who like it point out to the strong world-building, the realistic depictions of politics and war, the plot twists, and for having, refreshingly, an Anti Christ trope played completely straight for once. It's disliked for its lack of focus on Skulduggery and Valkyrie, the deaths of several popular characters, the reflection's role as new protagonist/hero, particularly as she's not well liked and her behaviour in the book just seems so out of character and the ultimatum given at the ending. Oh, and no Lord Vile.
Complete Monster: Nefarian Serpine. He was The Dragon of an evil wizard who started a war to revive Eldritch Abominations, and he killed the protagonist's family, then tortured him to death. However, after the guy somehow manages to come back to life and leads his side of the war to victory, Serpine double-crosses his old buddies by becoming The Mole and selling everyone out to get his own ass out of the fire. This, just so, many years later, he can get his hands on a super-powerful MacGuffin to start everything from scratch and kill everyone who even looks at him funny. It doesn't help that he only uses said MacGuffin on really powerful people because it kills them very fast and painlessly, while he prefers to kill everyone else in the most slow and painful way possible.
Crazy Awesome: Skulduggery refuses to give an answer on whether or not he is insane. Making that decision, he says, is the job of a psychiatrist. He is not a psychiatrist; he just punches people.
The Monster Hunters basically have a "who would you do?" discussion about the Dead Men and Frightening Jones (without realising that they're being overheard) in "The Malificent Seven". Frightening Jones is described as "gentle" and Vex's abs are admired.
Towards the end of Dark Days, it starts trending upwards and just keeps going.
Death Bringer. That is all.
Still on the up all the way throughout Kingdom of the Wicked. Just when you think they cannot possibly top the Argeddion vs Kitanna's gang vs Lord Vile vs Darquesse vs Alternate Mevolent fight sequence at the climax, Landy drops a sequel hook in which the reflection commits murder.
A chunk of the series has some of this starting out due to rampant Awesome McCoolname syndrome, though justified because everyone chooses their own name. The names "Valkyrie Cain" and "China Sorrows" sound more like Dick Tracy characters, but they make it badass. And the name Lord Vile sounds really Narm-y... Then you get to the end of Mortal Coil and you see Skulduggery break down at the sight of him.
Myra calling Fletcher a "flamin' drongo" was this for Australian readers.
Red Herring: We know that Darquesse is the true name of Valkyrie. Well, she has the reflection, right? Nope, it's actually Valkyrie herself. And then at the end of Kingdom of the Wicked, the reflection turns evil anyway.
The Reflection/Stephanie. Obviously it would always be difficult to design a likable Replacement Goldfish who's an exact clone of Valkyrie but her martyred, holier-than-Valkyrie attitude (despite murdering an innocent girl) and her place as new protagonist in Last Stand of Dead Men, despite the fact that she has precious little impact on the plot, has led her to become rather unpopular. The fact that she completely escapes punishment for the murder of Carol doesn't help matters.
Remnant Tanith and Billy-Ray Sanguine kissing. Valkyrie certainly seems to think so.
Even moreso when you think about it. Sanguine had a very creepy thing for Tanith for a while. Now, he's got an evil, possessed, fully consenting Tanith. God help the poor thing if/when she comes out of this stupor.
On a somewhat more light hearted note, Valkyrie flirts with a guy at the Requiem Ball. What she doesn't realise is that she has his drunk father's vomit in her hair.
Lord Vile sticking his thumb in Darquesse's eye.
The end of Death Bringer has Valkyrie biting that... thing to get it off her while they try to get away from Lord Vile. Even Melancholia stops being mean to her for a moment.
Darquesse gets her jaw burned off in Kingdom of the Wicked.
Have you ever read a detailed description of a human magically healing from decapitation?Do you want to?
Last Stand of Dead Men almost gives us a death by spiders scene. Which then turns into a graffic death by burning alive scene. But that was okay because the readers had already seen numerous people almost burned to death at the point and were over it. See What Do You Mean, It's for Kids?
Villain Sue: Darquesse is becoming one- as of Last Stand of Dead Men, she's able to take on armies and win without breaking a sweat. Some fans have complained that Landy is making her too powerful, and that it'll be too implausible to have her beat in the final book.
This series is advertised for children 9 and up. This would utterly shock the people who have read the series without knowing this. Particularly in later books, given the amount of harm Darquesse recovers from, including beheading.
Fletcher in Death Bringer, when he finds out that Valkyrie cheated on him. In Last Stand of Dead Men, his new girlfriend turns out to be a hitman, Valkyrie goes full Darquesse, his Australian friends die, Ghastly dies and, after making out with her, he finds out that Stephanie murdered Carol. Dude cannot catch a break.
Ryan from End of the World. Imagine finding out you're just a personality created by a criminal and that you're about to die.
Carol. He sister has an eating disorder, she has horrible self esteem and just when she begins to find herself, she gets murdered by Stephanie.
Ghastly. He's born with a cursed face, his mother is murdered by Lord Vile who is really his best friend, the woman he loves is permanently possessed by a demon and about to marry Sanguine and his friend murders him.
