I was like a 7/10 on part one, liked it, but didn't get the extreme praise.
This movie is ALIVE in ways that Dune part one was not. There is so much more depth and volume and scheming. I would say in the first movie, you're visiting Dune. In this movie, bring a stillsuit, because you're ON DUNE.
My wife kept looking over at me thinking I was asleep during the movie last night, because I was perfectly still with my mouth open the whole time. I was in a Villeneuve state of trance.
