The Assessment. B+. A mixed bag.
Spoilers:
Dependable, if graying, concept. Cromulent acting by 2 of the 3 leads. The 3rd, Alicia Vikander, is great for the first half of the movie.
In general, the first half of the movie is excellent. Then it starts to go hack and by the final act even Vikander is bad, but that's mostly because the script has become trite. They didn't know how to resolve it and didn't dare not resolving it. I can see them not wanting to rip off Brave New World any more than they already did. The scenery and set was a fine choice to avoid most of the redundancy of the concept.
The dinner is the best scene, even though the Basil Exposition monologue is atypically boilerplate.
There are well-executed homage SF set pieces throughout the film. I caught Stalker, Brave New World,1984, The Illustrated Man, and Fahrenheit 451. I'm sure there are more. Have fun treasure hunting.
A nice change from the summer children's movies, anyway. Ambition, even when unfulfilled, should be rewarded. Two cheers.
