I'm just laughing at his title, Bad Point No. 1:
He's obviously not a professional writer,
neither am I, just an amateur hobbyist. He's just appointed himself to spelcheck a novel, and forgot to spelcheck his review.
So, ironically, he made his point, and he made it badly.
"Now, don't get me wrong, the book isn't so bad that it's unreadable, but there are a lot of spelling mistakes, and there were a few occasions where I had to read a paragraph, read it again, and then reconsider what he was trying to say for a few moments before I could grasp the issue."
Also, run-on. If anyone should know that anything you post on the internet is going to be proof-written by pedants with nothing better to do, it should be a pedant with nothing better to do, on the internet.
I love irony.
