Well, I've read the first trilogy and I want to write my opinions, even if it's just a bit to get it off my chest.
In general, I have found the books to be good, very good even, but I think their final message doesn't quite convince me.
But well, let's break it down a bit. I'm going to go through the characters with POV, plus a couple more (Ardee and Bayaz).
I'm going to divide them into 2 groups: those who I think, in conclusion, gain more than they lose, and those who are the opposite.
They win more than they lose:
- Logen: Surprising, I suppose, but for me, one of the ones who comes out best in the end. Surprising, I suppose, but for me, one of the ones who comes out better in the end. I think the book ends with him starting the journey he tries to begin at the beginning of the first book before Bayaz gets involved. It's just that now he doesn't have the weight of revenge on him. Great scenes (the battle with the Feared, the reunion with Jezal), finally being Bloody-nine does not seem like a problem. And now he can try to be better in a new place with new people. Although it bothers me a bit that in the first book it's more magical than later, I'm thinking about the fire trick that is never used again.
- Ardee: I think it ends well, she manages to climb the social ladder, which I believe was a goal, and with none other than the most powerful man in the Union. I would say she is still alive, but the truth is that in these books, for how dark they are, few protagonists die. Although I wouldn't say it's her dream ending, basically climbing, but also having a husband she loves, not just appreciates (well, and who isn't a wreck of a human being), I think it fits well with the tone of the book. I'm not entirely clear on how she feels at the end when she says, "No one gets what they deserve," although I would say she believes she gets what she deserves, a bit tortured by her mistakes and sees this as a punishment/relief. I think the book would have benefited from having her POV since the female representation is a bit poor and she ends up being a bit of a puppy following other characters around.
- Dogman: I would say this is a character that ends up more neutral, Cathil's arc seems to me like a shitty use of female characters just to advance her pain, but well, she ends up far from the wars even though she loses faith in humanity in the process.
They lose more than they win:
- West: He ends up in a better position, being respected by the other commander and with his sister cared for and forgiving him. A shame he dies, otherwise he would be a true winner.
- Ferro: she acquires the power to carry out her revenge, but she gets completely lost along the way. Very bittersweet for me. Neither ends up having great moments.
And I think there are characters in these groups that I have left out, so I'm going to create two more groups.
Characters who only lose:
- Jezal: The biggest loser in the book by far (partly due to his own decisions, although I think this only applies to Ardee), but maybe I'm a naive romantic and have a preference for characters who start as idiots and improve, but I think he has very few victories. I understand that you are trying to make the plot about how following your dreams can be bad, and that you are trying to be realistic in the sense that actions have consequences, but I feel very sorry for his ending. He ends up imprisoned in a position where he can't help his people, even if he wanted to, with a woman who despises him (and semi-unconsciously rapes her). By the way, Terez is a terrible character too, not in the sense that she is evil, but because she is poorly written, once again a female character who only serves to give growth to a male one. And to top it off, her jailer marries the only person with whom she has had something resembling love. I understand why it tries to subvert the trope of the princess waiting for her prince and thematically punishes classism, but I think it goes too far, bordering on caricature.
And finally, characters who only win
- Bayaz: The great villain, I love to hate him. But he's a real bastard, he just wants to take over the world like a Disney villain. But even so, I like his trope of seeming like someone who believes the end justifies the means to a simple megalomaniac.
- Glotka: In the end, we come to Glotka. I know he is quite beloved in the fandom, but I haven't found him to be such a great character. On one hand, I don't find him that clever, just competent, and with plot armor. In the first book, he fails all his conclusions, in the second he only gets by because he has Bayaz's extra money, and in the third he does show a couple of moments of genuine ingenuity, like when he talks to Vitari about her children, but then the rest of the inquisitors just go along with it, he has extorted our "boss" so we won't do anything, even though if this goes wrong we'll lose our lives, as they say, plot armor. Logen also has plot armor when he fights, but he has a downside, Glotka only has it and that's it. He also forgives or executes people randomly (well, not so much, he has a preference for women, to be honest) but he never faces any real long-term consequences. If Jezal is a slave to his few bad decisions, Glotka makes quite a few more and nothing remarkable happens to him. He ends up being the most powerful man in the Union and married to a girl he likes, which also serves to torture poor Jezal a little more. And all this happens to him while being the most miserable man in the work, perhaps even more than Bayaz.
Ending with Glotka brings me to my big problem with the work; I just don't understand the point when it comes to choosing endings. One option is that decisions have consequences, but then I don't understand why many of Glotka's decisions have no consequences or why what happens to West has nothing to do with his decisions. If it's a bit karmic "no one gets what they deserve," I think it's a message of being cynical for the sake of being cynical, not lasting for being realistic, that the worst people fare better simply for being worse.
