I’m late to the thread and and didn’t read past the OP. Sorry for the drive-by, but wanted to toss in my own mini-review which I suspect includes ideas already thoroughly bludgeoned to death in the preceding 340-odd posts.
I saw this a couple weeks ago in IMAX with the wife (on a random Thursday afternoon when we had the nanny at home, such is “date night” with a newborn). We subsequently watched it the following Saturday at home with captions turned on. I really liked it in the theater. The wife, not knowing the book at all and generally being slow to grok fantasy world building stuff, enjoyed it a lot more at home with captions on and the ability to pause and ask questions. I mention this to highlight what I think is my main criticism of the movie, a lot of the dialogue is mumbled/whispered and delivered and utterly crushed by the film score. The score was magnificent, but it’s also overbearing. This problem utterly ruined Tenet, which was a bad movie. Dune is a very good movie that was made harder to watch because of this. That said, the sound WAS spectacular in IMAX so I get why they do it, but directors have to figure out how to communicate the story. In movies set in the real world, you don’t need to lean on dialogue as much, but in fantasy that tends to be how you build the world. This isn’t the first and won’t be the last to screw this up.
My second criticism is pacing. Villeneuve is a slow-burn filmmaker. I know this and it’s what a lot of people like about his movies. I usually like it. But I think he goes a little to far here. Part of this is simply a result of the story having no natural break point to end a multi-part movie, but it’s not only that. Everything leading up to the attack on Arrakeen was riveting, the initial assault was intense, but then the attack sort of fizzles out into nothing. Duncan and Gurney each sort of get absorbed into the chaos. Paul and Jessica end up on the 'thopter off screen. Leto is unconscious and wakes in his birthday suit. So much happens off screen. Then for the most part, Duncan, Leto and Paul get a coda…but that coda takes almost an hour.
Leto’s gas attack was cool, but very brief. Duncan has a couple really fun fight sequences but they don’t really change anything. Paul and Jessica eventually meet the Fremen and the Amtal scene simultaneously feels rushed and tacked on. The entire fracturing of the Atreides seemed like a unsatisfying end to the first installment. It’s important but I don’t think it was done justice…but it also can’t possibly be the crescendo that the attack was, so from a pacing standpoint the movie felt unnaturally truncated in spite of feeling over-long.
Had I been in charge, I think I would have ended the movie right after the attack. The final scene would either be Paul and Jessica flying off to certain doom in the 'thopter with the Harkonnens or Leto poisoning the Baron and Piter. From there you’re left with the cliffhanger, is the Baron dead? Will Paul and Jessica survive? Of course, you know they have plot armor and will be back, but it works better narratively. And you can extend the fight scenes for Duncan and Gurney, you can show how fearsome the Sardukar are supposed to be, you can give Thufir something to do at the finale. Then the next film picks up with Paul and Jessica making their escape and starting their integration into the Fremen. I think it all works better (but I know that you need to give Zendaya and Javier Bardem screen time).
The last criticism I have is with way the executed Paul’s visions. Honestly, it just didn’t work that well. They seemed to slow down the movie during what should have been it’s most exciting moments. I first noticed the issue with the Gom Jabbar scene…Paul’s experiencing intense pain and believes his hand is being burnt down to bone. But the presentation here doesn’t really communicate this message that well. Timothee’s acting is fine, but the visuals don’t really explain the horror of it. In this one small area I think the Lynch version is more effective. Similarly Paul’s various visions were just confusing. I know that’s sort of part of the point, Paul’s confused by them at first, but they were scattered and misleading. I don’t know exactly what the best way to handle this is in a movie, but Denis’ solution didn’t work for me. That these visions occurred during the action sequences I think killed some of the energy and drama of those sequences. The rescue from the sandworm I thought especially was adversely effected.
So, those are the criticisms. That said, I really really liked the movie and will probably rewatch it a few more times. I’m excited for the next installment. But, my praise isn’t going to be that interested to read at this point (he says pretending the previous paragraphs are interesting, heh).
