Dune
I enjoyed it. There was a part in the first third that started to drag slightly; I wanted them to get on with the action (too many Marvel movies).
Comparing it to the Lynch travesty version, this is altogether grittier. Sandworms, you will be pleased to hear, are intimidatingly huge. The ornothopters are absolutely brilliant, look entirely feasible machines.
They managed to communicate the politics of Dune without labouring on.
The only miscasting casting (for me) was Thufir Hawat. Didn't convey the calculating detachment expected of a Mentat.
