...I make no promise that I will post a review, so if I really don't like something, I don't review it.
With an academic background in writing and teaching, I can hone in on the material and not sound as if I'm grilling the author (because I'm not). I think reviewers have an obligation to give a balanced view of the material, pointing out what they liked, but also pointing out what others might not like (e.g. "The violence may be too much for some, but I found it appropriate to the story").
