It was okay, but flawed. Some of those flaws:
Jessica was a wimp when she should have been badass.
Duncan was woefully miscast (Spoiler: doesn't bode well for future films).
Gurney Halleck was barely present.
Mentats where not explained.
The director expected the audience to be bowled over the climactic giant sandworm. News: it's 2022, we have seen it before.
Sand. I don't like sand. It's course and rough and irritating and it gets everywhere.
On the other hand, Timothée Chalamet was great as Paul, and the Ornithopters where great.
