I didn't downvote Tiiba, but there's lots of reasons I could have potentially downvoted her, besides simple disagreement -- from the hostile tone all the way to a confusing semi-rhetorical "Does he?" at the end, which didn't make it clear what exactly she was asking us about.

If Tiiba was asking us, if given her hostile reaction, she should anticipate her opinion of the work to improve later on, she could make it far clearer. If Tiiba was asking us if there's justification for the content of the chapters she has read so far, she could ask about that more clearly as well.
