I really liked the first half of this movie. The world building was fun and interesting, the sets were unique, even though you could barely see them half the time. Apparently, light bulbs aren't a thing in the future.
I liked the characters and the story but then it just starts to drag and drag, too many scenes of the characters just wondering the desert, trying to get to the Fremen, something that would have taken a few minutes in most movies. But then I remembered this is only part one which means they stretched it out on purpose. By the end, the movie didn't conclude in any meaningful way, it just stopped and said "see you next time." And I'm pretty sure there won't be a next time. shame. I really like Denis Villeneuve; Arrival was my favorite film of 2016 and Blade Runner: 2049 was my favorite film of 2017, this one just let me down.
