Yeah, it's so good! The ships in it are really well written. Have you read S&B or KoS yet? 

I really like Kaz and Inej too, and also Nina.

Spoiler Ahead:

It was so sad that Matthias died    don't worry Nina finds someone else in KoS though. BUT STILL!!!!!! *sobs internally*

End of spoiler

I really like those ships too. The first one you mentioned (I'm not saying it because I'm to lazy to put another spoiler warning) is SO AMAZING oh wait I do need a spoilet alert ok here Spoiler Alert it's so funny that they both sort of have trauma with touching people because at one point there's a quote that;s something like "The two toughest people in Ketterdam couldn't touch each other without both of them keeling over". they are SO perfect for each other! Then at the end, when Kaz gets her a ship and her parents, it's like, WOW so you are capable of doing good things I knew it! end of spoiler

I personally thought SaB wasn't as good as SoC (that is one of the main causes of arguments with my friends, also including: Band Kids vs. Orc Dorks, Harry Potter vs. Star Wars, and Scouts vs. Girl Scouts. try to guess my opinions on each of those . . . ). I REALLY recommend KoS, it pretty much combines a bunch of good characters (although Inej and Kaz are barely in it, only mentioned a few times and Kaz is in it once) and really good ships, and also VERY important information about the GV in general hint hint: dragons, saints, wars, marriages, etc. You might want to read SaB agian though, if you forgot a lot of it, bc it has a lot of those characters. I think the main POVs are Nikolai, Zoya, and Nina, then some are added on later in the series, like new characters and stuff 

wow this post is so long . . . sorry that some of my sentences are a bit weird I think I sort of went crazy halfway through. I just really like these books.  

oh, and about the TV show, I started watching the first episode once. This was before I read SoC, but they had the AUDACITY to COMBINE THEM EVEN THOUGH THEY ARE SEPARATE TIMELINES! So of course I was like, wait, Six of Crows people? Oh no! This makes no sense! 

And it was made even worse by weird things like: Alina was half Suli and people didn't like her because of that, and...I forgot. I think I stopped watching it after that. But I might try again soon. 

I actually agree with your second point (and your first point makes sense, but I love Kaz and Inej, how their relationship is mostly that they're just there for each other (excepting the one scene, which was still amazing, and not rly an exception), how they move on at the end as if just knowing is (at least for Inej) enough, their characters in general (though I am partial to amazing strong capable female characters, especially ones with cool names like "the Wraith", but they also just have amazing backstories and development and motivations and personalities and are just so real)... and you rly can't help but love a (fictional) ruthless mastermind who is amazingly smart and knowledgeable and... well, just when you hear Kaz's plans, it's like, HOW?!?, and everything both of them say is a gem "when people know you're a monster, there's no need to do every monstrous thing" or whatever, and.. this is turning into a rant about them so yeah), ANYWAYS, yeah, I feel like Leigh Bardugo could've done more with Matthias's character, but she didn't, and then SPOILER killed him and ended any more possibility for development 

END OF SPOILER and honestly, he was my least favorite of them all, and he really does seem like Leigh just put him there for Nina and maybe to share a bit of a diff druskell pov (I didn't really love him and Nina either, or Nina in general, though I like how she is with friends). However, I do have two quotes (off the top of my head, there're prob more) from him that I love, where I rly appreciate what he brings to the team, so maybe he isn't entirely pointless:

Kaz leaned back. "What's the easiest way to steal a man's wallet?"

"Knife to the throat?" asked Inej.

"Gun to the back?" said Jesper.

"Poison in his cup?" suggested Nina.

"You're all horrible," said Matthias.

and

Jesper knocked his head against the hull and cast his eyes heavenward. “Fine. But if Pekka Rollins kills us all, I’m going to get Wylan’s ghost to teach my ghost how to play the flute just so that I can annoy the he** out of your ghost.”
Brekker’s lips quirked. “I’ll just hire Matthias’ ghost to kick your ghost’s a**.”
“My ghost won’t associate with your ghost,” Matthias said primly, and then wondered if the sea air was rotting his brain.

And for some more about Inej and Kaz... I just finished the 2nd episode of Secret Invasion (MCU) today, and it hit me how much Gravik and G'iah are like Kaz and Inej! Which made me like the show a whole lot better (funny how that works...).

For ex:

- they all have traumatic pasts

- Gravik and Kaz both have a hard k sound (also Brekker), which just makes them sound more ruthless for some reason

- Gravik and Kaz are kinda both ruthless masterminds

- Gravik and Kaz both kinda run the operation

- G'iah and Inej are both kinda the second-in-commands, and the former both seem to kinda just expect them to be there, helping them and being loyal and stuff, not always saying thank you

- Gravik and Kaz both give harsh punishments and aren't afraid to kill

- Gravik and Kaz both have lost their parents, and losing a loved family member(s) has made them who they are, and brought them where they are, they are fully committed to a cause

- Gravik and Kaz both seem to really genuinely care about G'iah/Inej

- G'iah and Inej seem to have killed a whole lot of ppl too, but... idk, seem less... receptive? Meh?... to it. Or idk about G'iah though, but that car scene in the woods in episode 2 made me think so

- In both they (just an in general they) SPOILER kill someone who is or was on their side (that guy who talked in episode 2 and Big Bollinger), which, again, G'iah and Inej didn't seem as fine with END OF SPOILER

- they're all rly capable and have reasons for what they're doing and I like them

- G'iah and Inej both seem to be kind of silent and the finding-out-information type

- G'iah and Inej both seem to be one of, if not the, shortest

-Gravik and Kaz both are true about keeping deals and such 

- just all their personalities and demeanors and vibes and situations make me connect the groups and characters 

btw, I haven't watched the show.

also btw, I feel like Kuwei is ignored a whole lot of the books. And isn't treated as nicely. And is the reason I don't like Jesper and Wylan as much even they are pretty cute together, bc of that whole incident. And... well, yeah. I felt like he was just kinda there to create some drama for Jesper and Wylan too

another btw, I can't agree with your third point, that's from another book, right? I've only read the SoC duology. ... this is long sorry admins I'll stop now

woah!!!!!!!!! That's so weird! I think it maybe wasn't intentional, because I looked up why the book was called that and it didn't say anything about that rhyme. Of course, it might have somehting to do with crows generally representing scavengers, which I did see something about, but still! That's really interesting. 

I've seen parts of the series, but not the whole thing and I it was just kind of... meh. It tries to combine SoC and SaB into the same series, so it's pretty confusing when it jumps back and forth. All of the characters portrayed are also just really old-looking and don't fit the characters at allll. It's also fairly mature—blood, violence, dark stuff, etc. (you probably know this but just another warning).

If you want to try it, go ahead, but I definitely wasn't attached to it.
