So yeah, the modern-day and future sections of this are basically lifeless fluff. They're not visually interesting or dramatically compelling. The film tries to wring some pathos out of the self-sacrifice of an AI, which I doubt would have been well-received in 2023 when this film was shot, and certainly doesn't land in the year-of-our-lord 2026.

Still, I've got to give this film credit for the prehistoric sections. The story of the neanderthal family teetering on the brink of extinction is genuinely charming and, as far as I can tell, scientifically well-founded.

Completely fucking odious movie. A throw-back Pulp Fiction rip-off from the late 90s, but with the absolute shittiest plot imaginable. An entire film based around the idea that we give rape victims too much credulity. I would have felt sick if I'd paid to see it.

This kind of felt like a bit of shrug by Errol Morris. It explores a few different angles and introduces some interesting tidbits, but it's never that convincing and Morris clearly wasn't convinced either, so in the end the only conclusion that can be drawn is "welp, people just want to make sense of things."
