Dunes.

“As with all things sacred, it gives with one hand and takes with the other."

Frank Herbert, Dune Messiah

Provided that Dune: Part 2 continues its success at the box office, a third Dune movie based on the second book in the series*, Dune Messiah, will probably get the green light for production in the near future.  (This is a little confusing - I wish that Denis Villeneuve had used a different numbering convention for the two Dune films, perhaps Dune 1A and 1B.)

I have mixed feelings about this. Out of the six Dune books written by Frank Herbert, Dune Messiah is arguably the weakest one. It's the shortest of the six, lacking some of the depth of the other books, and has a sort of rushed feeling about it - I've always suspected that it was written in a hurry so as to take advantage of the popularity of Dune.

Regardless, even at his worst, Frank Herbert knew what he was doing, and Messiah capably sets the stage for the rest of the series - which, logically, means that there could easily be at least one more film after that.  Hopefully M. Villeneuve won't split Children of Dune into two parts, that won't help with the confusion factor.
