Disliked a novel I had to judge. Very meh. Not bad, but not good either. My issues were all craft related: the whole story is told in conversational First Person, too many POVs and characters (I almost needed a spreadsheet to keep up), story beats were underdeveloped and came way too late, which had everything lagging, etc
So I went to see what others had to say and everyone else loved it. Raving 5-star reviews for the series.
This is what happens when authors read. The inner editor is always critiquing.
