This made me think about why Rowling's books work. I think part of it is that they have so many cool ideas in it. Let's take book 4: we have the quidditch world match, the tournament thing, the crazy tough auror as a teacher, and the sensationalist reporter. All of that stuff is exciting, and in the end all of it contributes something to the plot. The fact that quidditch is the worst game ever invented, Voldemort's plan had 1000 ways of working without the tournament, and that the auror thing probably shouldn't have made it passed safety precautions of the school doesn't make that much of a difference.
And I don't even have a complaint about the reporter. Props for having the reporter be the bad guy!
also, it's not just that the ideas are good, but the exceution is good as well, isn't it? The quidditch world match didn't feel like "and then they went there and this thing happened", it's this entire arc that feels alive and is full of character moments and details
