If you didn’t care for the first movie I don’t think the second will solve any of your complaints. I say this as someone who really liked both movies. I have criticisms, and I don’t think they’re close to being Villeneuve’s best work, but the worst Villeneuve movie is still better than most directors on their best day. But two is very definitely more of one, and if anything it amplifies the first movie’s flaws rather than diminishing them, so it’s very unlikely to address anything you didn’t like. That said, I will throw it out there that it may be worth watching anyway just to experience Austin Butler’s incredible take on Feyd Rautha, which is easily the best thing about the movie.
I think the choice to set up Aliyah but ultimately leave her arrival for another time was a smart one, just as it was smart to not introduce Feyd until the second movie. Doing so really let him arrive in a big way, like “Oh shit, this guy is important.”
(Also good lord, Austin Butler steals the second movie so hard)
I think that’s a significant improvement. Chani being “ride or die” in the books is an awfully charitable way of saying that she basically has no purpose to her existence outside of Paul. The movie choosing to have her really show some resistance to the shitty / crazy stuff he’s doing gives her more inner life as a character. It also nicely sets up for Messiah where there’s definitely some tension between her and Paul (though never sufficiently explored IMO) over his choice to make Irulan his wife.
