Summary: 9/10: thrilling, funny, emotionally resonant sci-fi that uses its high concept to ask essential questions about cooperation, sacrifice, and whether we can save ourselves before it's too late.

I hadn't read Andy Weir's award-winning novel before seeing the film, so I wouldn't be disappointed by the adaptation. And I wasn't. The Lord-Miller team, Phil Lord and Christopher Miller, made this an exciting and rewarding sci-fi film that captures Weir's science-heavy problem-solving while never losing sight of its emotional core.

Ryan Gosling totally nailed the sardonic scientist, insisting on playing someone not good at being in space, someone who flips out and feels clumsy in zero gravity. His character arc, from isolated problem-solver to someone capable of profound emotional connection with Rocky, a sentient rock-shaped alien, is beautifully rendered. Gosling brings vulnerability and humor to a role that could have been purely cerebral, making Grace's transformation genuinely moving.

The premise of the film carries urgent relevance: we humans can survive only within a rather narrow temperature range. Project Hail Mary presents a cooling scenario, but the existential threat is the same whether we cool or overheat through global warming. The astrophage consuming the sun's energy becomes a metaphor for the forces draining our planet's capacity to sustain life.

According to a study published in Nature, almost two-thirds of global warming is caused by the wealthiest 10% of the world. Our time is running out, and this film functions as a call to action: we need many heroes like Grace and Rocky to step up and wrestle our future from the wealthy capitalists, monopolists, "kings," dictators, and other "astrophages" consuming resources without regard for collective survival.

Lord and Miller, working from Drew Goddard's screenplay, balance the novel's technical problem-solving with genuine humor and heart. The film understands that science fiction at its best isn't just about solving equations; it's about what we're willing to risk, who we're willing to become, to save each other.

Regarding the last sentence, that's ship time, on earth it would be over 12 years. Someone can do the math to figure out how many earth years, but note that the ship seems to accelerate at around 1 g for half the journey, getting very close to C, then flips and decelerates for the other half.

Weir released the spreadsheets he used for all the calculation

Can't check right now, but I'm pretty sure that the time dilation calculation is in there as well

This more or less covers it, in the book it is described in more detail. If you enjoyed the movie, I can recommend the book for more science background information.
