bad reviews on Onyx Storm

I just finished Onyx Storm last night and I can’t for the life of me figure out why so many people hate it? Like people saying it’s bad writing etc…

Now i’m no literary genius but I was thoroughly entertained and I’m dying to find out what happens next! For all the haters of this book, I would like to hear your thoughts on why you/a lot of the community dislikes the book.
