Cool reviews! You didn't ask, but here's my opinions on the ones I've read:
The Sorcerer's Stone:
Gonna have to disagree with you here. I haven't read this one in years, so I won't be too long here, but from what I remember, this one nailed the "pulling the reader in" bit. I think the easy-to-read thing is worth more than you're giving it credit for, Rowling's greatest asset in my recollection is that the writing is immediately engaging no matter where you open the book to.
Even more than any of the other novels, though, this is definitely a children's story written for children and aimed at children. It might not be as engaging to someone reading it for the first time at an older age.
I agree, this is a really good book. It had a number of twists and turns, but nothing ever felt out of place or unforeshadowed. Ender's story alone could have made an engaging novel, but what really impressed me here was how Card weaved in the earth politics through Valentine's chapters. Those were some of the most intriguijng parts of the book, and knowing what was going on in the background of the world made Ender's chapters all the more significant. I thought this book did a great job with balancing the violence it had. The plot needed aspects of brutality in order to have any meaning, but all the violence that happened existed to serve the plot and the characters. A lot of other books will make the mistake of shying away from showing the necessary violence, or instead going over the top and making the reader wonder why any of this matters.
Haven't read any of the sequels, though. Are they worth it?
Stephen King starts this book by saying that all books on writing are full of bullshit, and then proceeds to write the most singularly helpful book of writing advice I've ever read. Putting the memoirs and advice in the same book was a great idea, because it makes it all the easier for the reader to see how and why what he's saying makes sense. It's more engaging than plenty of actual fiction books.
Rythym of War:
I'm only halfway through this one, but so far I would tend to agree that it's not quite as good as the others. That said, it's hard for me to imagine something managing to top Oathbringer. So far, I like that we're getting to see more of the parshendi, and am not really interested in the ghostbloods.
From what I've read about him, King is the kind of author that never seemed to want to outline and plan his stories that much. So that might be the reason why his beginnings are so strong, but fail to deliver a proper punchline. Frequent uses of asspulls, deus ex machina and such.
Though Robin Ellacott’s twenty-five years of life had seen their moments of drama and incident, she had never before woken up in the certain knowledge that she would remember the coming day for as long as she lived.
This reads like onoe of those sentences the english teacher writes on the whiteboard at the start of class, and then says "Okay now spot the 132 mistakes".
Gotta agree with you on that point. Harry Potter is the kind of book series that you have to read before you are eleven to properly get into it (I did). If you read or reread it or even browse the wiki page as an adult, then you may realize that the little of barebones plot that there is, all serves the sole purpose of being a child's wish fulfillment. That's the reason why kids like it so much and why adults find these books hard to read through (so many pages wasted on doing nothing but dicking around in magic school).
Glad to hear that you support TERFs.
Another great thing about the series is that she leaves clues about future events SEVERAL BOOKS before.
I don't think cinnamon phrased it very well, but multi-book foreshadowing was something Rowling was particularly good at. Plenty of authors effectively do multi-book shadowing by including a vague event that is later explained, but Rowling was able to do it in a much more subtle way than usual with casually mentioned details that seem like they were only brought up for worldbuilding or a one-off joke. It's always nice when an author foreshadows events that way.
