Not for everyone - relentless, violent, quite long, & utterly bonkers, not your average plot-driven sci-fi at all. Closer to experimental film than one ever expects to see in a film on general release. But also profound & moving, touching on really relateable family issues, the effects of severe stress, the implications of ideas about the multiverse, and the dreadful state humanity has got itself in. We loved it, and clapped at the end of the credits. The other couple who had stayed right to the very, very end joined in.
