I'd read it. I read Book 1 and I
don't hate it at all. As I've said in my brief review (post #517), the writing is not that bad. Just a bit repetitive. I can see how some writers may feel a bit miffed because they spend all this time and effort crafting their prose, and suddenly this novel with "bad" writing pops up and blow out sale records.
But I'm definitely in the minority at this forum, so you may want to discount my judgment heavily.
I heard Book 3 is the best and Book 2 is the worst from a couple of people.
I think it's good to read it to be part of the zeitgeist. It's such an incredible word-of-mouth phenomenon that I want to know why people are reading it. As an aspiring writer, I figured I can learn what the market likes. I also like to be part of the conversation, and I can't do that unless I read it.
