Reviews like that stink.
The first review of Untrustworthy
was a DNF (did not finish). This was a reviewer I had sent a copy to.
And the review was obviously based on just what you can see with the Amazon Look Inside feature.
Shitty, careless reviews like this can gut an author, and make them want to stop writing.
I firmly believe that they are the same kind of abuse people heap on waitstaff and clerks, the kind of nasty behavior that far too much of society thinks is acceptable and doesn't detract from their personal views that they are good people.
News flash: they aren't.
Second news flash: writers don't (or at least they shouldn't) expect rave reviews all the time. But there's a vast difference between a review that says characters lacked depth or the plot was predictable or the accents were hard to read versus being an asshole to a writer to make you feel better about your miserable self.
PS congratulations to the kid and his bride!
