Margaret Atwood's novel is rarely about just one thing, but the reviews I've seen circle a few core ideas relentlessly. The most obvious is scientific hubris and its consequences. 'Oryx and Crake' presents a world where corporate biotech has run utterly amok, creating custom organisms and commodifying life itself until society collapses under the weight of its own 'improvements.' It’s a chillingly plausible bio-apocalypse, not a nuclear one. Crake, as the archetypal 'mad scientist' who believes he's solving humanity's problems, embodies this theme completely. His logic is cold, rational, and utterly horrifying in its conclusion that the best way to save the planet is to remove the primary parasite: us.
Beyond that, reviews consistently hammer on the commodification of everything, especially the body and intimacy. The book's setting is saturated with pornographic websites, genetically modified 'perfect' partners, and a complete erosion of emotional connection. Jimmy's obsession with Oryx, who herself is a product of this system, is a tragic symptom. Reviews often analyze how Atwood uses this to critique a culture where even rebellion and 'art' (like Jimmy's work in the slogans) are just absorbed into the commercial machine. It's less about the technology itself and more about what we choose to do with it when all moral and social guardrails are gone.
Finally, I think a lot of reviews spend time on the theme of memory, grief, and storytelling. Snowman, as the last man, is literally clinging to the old world through language and fragmented recollections. His entire existence is an act of bearing witness. Reviews highlight how the narrative structure—jumping between past and present—forces the reader to experience this haunting contrast between a vibrant, awful past and a silent, emptied present. The most poignant question the book leaves isn't 'what happened?' but 'what is worth remembering?' The Crakers, with their purged 'bad' traits, represent a new beginning, but one that seems sterile and childlike compared to the messy, flawed humanity Snowman mourns. Ultimately, the review discourse suggests the book’s power lies in how it makes you mourn a world you’re actively living in.
