I am having a question roughly along the lines of the following in mind:
What are the inevitable plot holes in Frank Herbert’s Dune writings?
I read the first Dune novels in pretty quick succession and while the universe is consistent at large, there are a few prominent plot holes, such as discrepanices on the nature of navigators or the requirements and effects of pre-born-ness. Given the nature of the novels, in particular their reliance on consistency, these were unpleasantly confusing to an extent that in my opinion justifies the efforts of creating a list of them. Having such a list would have been something I would have welcomed and also would like to have for a possible re-read.
Hence I am asking: What are the generally acknowledged plot holes in Frank Herbert’s Dune series? To keep the list short, useful and subjective, answers must comply with the following criteria:
- It’s really a plot hole, i.e., it’s relevant to the plot and not just an athmospheric side note. For example, if somebody’s hair colour changes without explanation, this is only a plot hole if it is relevant to the plot.
- It’s really a plot hole, i.e., there is a clear contradiction here, to which no satisfying in-universe explanation exist. In particular, plot holes of the “why don’t they?” type are not permitted. Preferrably, the plot hole is generally accepted. [Alternatively: There must be a question about it on this Stack Exchange that did not came up with a good (insert vote criterion) in-universe answer.]
- It occurs within the six original Dune books by Frank Herbert. Short stories, deleted passages, the Dune Encyclopedia or writings by Brian Herbert do not count into this.
For those not familiar with Dune: This is about six books by one author, who did seem to strive for consistency, and just seems to have failed to remember certain aspects. I personally estimate the number of such plot holes to be between five and twenty. I am not suggesting that asking similar questions about the Star Wars, Star Trek, the Discworld or Doctor Who would be a good match for this site (though some claim that there is a small finite number of plot holes in the new Doctor Who).
- Would such a question be acceptable?
- Would the answer to the above question change, if I only allow for answers “backed-up” by another SciFi.SE question?
- If such a question in any form is acceptable, how should the answers be organised? One anwser for everything or one big community-wiki answer?
