I will know the hand of the sinner that brings forth the strangling fruit of inconclusive fiction. The wretched of the light will stomp mightily on the sinful authors of ambiguous trilogies and send them screaming into the eternal hell of publishing corruption while the worms giggle and chew energetically on the flesh of the accursed author....
I started reading the Southern Reach trilogy (Annihilation, Authority, Acceptance) a year ago without realizing it had not all been published yet, something I swore to never do again after a bad experience in my youth involving Zelazny's Nine Princes in Amber. (1) But having started reading this series and finding it compelling, I ordered books two and three from Kindle and binge read them when they were released. I was right to suspect that this was going to be a messy ending. What does messy mean? It means that many of the mysteries of Area X and the three books of the Southern Reach Trilogy are not resolved by the end of the third book. In fact, new mysteries are added by the third book extending the cause of anxiety-producing lack of closure.
The worms will dance in the brain of the sinners who fail to resolve important plot points and bring forth the seeds of the annoyed who will jump up and down and never forgive ...
The seeds of the annoyed will emit glowing clouds of vengeance that will plotz on the author and cause him/her/it to rue the day....
Those who have read the trilogy or do not mind spoilers may read a partial list in the notes (2).

The unknown plant will bring forth the seeds of the dead who will stomp on the fingers of the readers who believed that there is meaning and rational causation in the universe that they can understand but that is not the case.
