I'm laughing at some of the complaints here. That review is mild, as far as I can see. I have seen and received much harsher criticisms than that. And clearly she's liking the novel enough and is giving out good feedback and suggestions AND leaving a review of 3/3.
And not only that, instead of thinking about the criticisms, he let it get personal and ended up confronting her about it. That's even more idiotic. Actually, thinking more about it, he's a total idiot for letting it get personal. If he does that shit when he becomes a pro (IF he becomes a pro with that attitude), he's going to be in for a really rough ride.
