A Dance with Dragons
I had actually never picked this up, feeling pretty worn-out after the previous book. Luckily a lot of my complaints of the other books weren't too relevant so far--the first few chapters were Danerys, Tyrion, Jon (and a prologue, but a prologue where someone jumps bodies between humans, so it was still moderately interesting).
That said, my reaction after reading the first few chapters was "this book sucks, I'm going to try the other book I bought which I knew nothing about on buying." Aaaaand I kinda ended up reading that entire series and forgetting about A Dance with Dragons.
Lunar Chronicles Series
So...this entire series is a sci-fi re-imagining of fairy tales, often heavily re-done to the point that you really don't know what's going to happen.
Actually I'm going to break this down by character rather than by book or fairy tale inspiration.
Cinder: She's a cyborg, she's a mechanic, she's badass, and overall honestly probably the most compelling character in the series, or in the running. Which is good when you're the main character.
Scarlet: If I have a criticism of Scarlet, it's that she sometimes feels like her personality doesn't differ enough from Cinder's. I mean, yeah, she's a pilot and not a mechanic, and a farmer who uses a shotgun, and she doesn't have Cinder's various superpowers. But they both mostly fill the niche of badass competent protagonist. This would also explain why they're not often in the same place at the same time.
Cress: Best programmer in the solar system, and constantly upbeat and ridiculously idealistic. I feel like I -should- looooove Cress, but...I honestly think she's the weakest of the four main characters. I think part of the problem is that she's taken out of her element a lot, which admittedly isn't hard (get her away from a computer terminal and she's pretty useless. Get her computer access and she's god). I also felt like her romance subplot kind-of grated at times. (I mean, it's not a computer terminal, so she's really bad at it, but then that means it takes a long time for that arc to resolve...).
Winter: OK, Winter can maybe compete with Cinder for best character. I don't even want to give anything away about the character, but she actually is really visceral, and I like her implementation.
Kai: Eh...I'm pretty lukewarm on Kai. Like...in theory everything about him is fairly likeable (the fariy tale character he represents is Prince Charming after all). But he's part of a number of some of the slower more political chapters (pulled out whenever we need a perspective into global politics). And he also gets damseled a lot. Really, there's nothing wrong with his character, highly competent, empathetic, etc, but he gets used as storyline glue a lot.
Dr. Erland: a.k.a. Doctor "Ends justify the means". Honestly, I think he's an excellent morally grey character. I really ended the series thinking he's a total asshole. But would the world have been better without him? Probably not, to be honest.
Captain Thorne: He is a walking clichee, but he's a likeable walking clichee, and he does actually have genuine character development. Can't really complain.
Wolf: In a series where the male characters are sometimes sidelined, he's probably the best male character. His character arc has a lot of highs and lows, and some fairly unexpected twists (to me).
Jacin: Hmm...honestly he exists to be the straight man. Hugely eclipsed by the characters around him, he's kind-of just a normal dude.
Levana: I actually haven't read the side book about her yet (Fairest) so I'll reserve judgment. Excluding that, she's like...comic-book levels of evil.
Aimery Park: Although Park shows us that being a comic-book evil henchman can be done with some spice. He's genuinely twisted and deranged, instead of just being efficient like Sybil Myra.
