If anyone could make a great adaptation of Frank Herbert's book it was this magnificent director that is Dennis Villeneuve.
The cast is spectacular, I think everyone fits perfectly (watch out for Rebecca Ferguson's role), the script couldn't have been more faithful, the sound is amazing. And visually it is on another level, I have rarely felt that way in the theatre (and usually with films by the same director).
Btw, 6th time I have watched this film! 👌
