All right, I caved - we watched it last night, and I'll probably watch it again on HBO or possibly in the theater if I can get my wife on board. (long shot)
So the look, atmosphere, 'feel', aesthetic of the movie is OMG spot on. Absolutely magic. Everything is huge, and super detailed, and feels very 70s scifi book cover all over. The ornithopters actually have wings! Awesome design. Just everything. There's no "weirding modules" thank goodness. I don't recall any specific references to the Weirding Way, so TBD on that point I guess. I can't say enough about the whole 'lived in' feel of the universe. There are so many amazing shots in the movie, it just pulls you right in.
That said - much, muuuuuuch of the film owes a ton to the Lynch version. I love that version despite all its flaws, but overall I felt like this film made a lot of the exact same mistakes. They did make the decision to slow down the story, and try to set the stage at a slower pace so you could more thoroughly take it all in. That worked, I felt. However, it has the ultimate effect of making the film sloooooooooow. Don't go in expecting action, action action - this does hold true to the book in all the political intrigue; slightly less hit-you-over-the-head than A Song of Ice and Fire, but also less detailed (I mean, it's a movie, not a 500 page book). I kept thinking "this is what the Phantom Menace was trying to be," with all the political machinations going on. That stuff worked much better in this film.
There are 3 fight scenes I can think of, which were all fine. I was a little disappointed with Gurney and Paul's training scene, I just love the special effects in the Lynch one, which were toned quite down. There is one particularly AAAAAMAZZING huge battle scene. That was just so well done. The Harkonnens are given very limited screen time, which I thought was smart - it makes them a little mysterious and sinister.
All in all, I thought it was actually pretty good - However: My wife hasn't read the book, and hadn't followed any of the marketing. Like Ted (and I bet the vast majority of the audience), She didnt' realize that it was a "Part 1", and she was kinda pissed when the movie JUST ENDS. Almost in the middle of a scene, too.
I realized how incredibly brilliant Peter Jackson and crew were when they pulled together the structure of LOTR to those 3 films and made decisions about changing where certain scenes landed in order to serve the film. Great decisions.
So I REALLY enjoyed this movie - but I'm a big fan of the series, and I think there is a miniscule chance this makes enough money to warrant a part 2. I think the filmmakers had blinders on trying to be so true to the book that they forgot to make a compelling film. I'll rewatch it again and reevaluate.
