But I think even you can acknowledge that you can't give an informed opinion on the quality of the books without reading them. At best, you can express your disinterest in finding out.
But that isn't the point; no one has said the any of the books since Before Dishonor
were badly written. What they have said is that we do not have any interest in reading books set after Janeway's death because we don't want her dead. That is a criticism of the "direction"
of Trek Lit not a criticism of the writing and we do have the right to express our displeasure over the "direction"
of Trek Literature without reading anything first.
Exactly my point too.
As for Voyager books, I love the season 1-3 books (read my mostly positive comments about them at the Kes Website)and some of the early relaunch books were acceptable, if not as good as the season 1-3 books.
