FYI, multiple spoilers, of both the second movie, as well as the overall story, in the article for those who have not read the books, but have seen the first movie.
(Yeah, I know, but still, I'm sure there are some people out there who fit the description I stated above.)
Good article, worth the read.
From the article...
We’re also reminded of another thing Villeneuve told us this year: “I always have been, since I was born as a filmmaker, concerned, inspired, and sensitive about the female condition and women’s relationship with power.” He even went on to say he wanted his movie “to be an adaptation about the Bene Gesserit. I want the Bene Gesserit to be at the center of the epicenter of this adaptation.”
