I am glad that the movie didn't do that, I liked it precisely for the reason that it made me the fly on the wall of a greater story. I know we are used to get likeable protagonists, but ultimately I often perceive these as cheap tricks that take away from my feeling of immersion for a place. Because all the usual plotpoints and hyperfunctionalized narratives ultimately tend to turn the world they take place in into exchangable backdrops, which is the polar opposite of the idea of the Dune series, where a Place (Arakis) influences the lifes of whole societies in interesting ways. I am glad that Villeneuve managed to do without the classical Hollywood-Three-Act-Script-Consultant-Techniques that make so much of todays movie production bland and unwatchable (for people like me), precisely for the same reason: I can't care for stories where I feel the cheap tricks that make it up at every corner.
