I saw it in 1984; fell asleep (seriously). Watched it again over the years and it is in my top ten. The author of the article insists Paul became a superman? Or (and I am way out on a limb here) did it rain because of the massive sandworm activity, creating so much atmospheric dust and electrostatic lightning, creating larger nucleating particles, causing it to finally rain? Admittedly never paid that much attention to that part, just the ambiance.
