30 years from now, the earth and its population are collapsing because we’ve used up all the resources and the habitable areas are diminishing because of the effects of global warming. As humans so often do in science fiction, and in true life non fiction, instead of fixing it, we’ve left it too late and aim to abandon it, looking to the stars for relief.

In this case, we’ve got our sights set on Saturn’s moon, Titan. Only instead of terraforming it, we’re terraforming ourselves. Or rather: an ambitious doctor is leading a military experiment to genetically enhance humans to make them more suitable for Titan’s harsh living.

Joel (Sam Worthington) is one of the chosen few, so he and his family, including wife Abi (Taylor Schilling) and son Lucas (Noah Jupe), move to the military base where he and his fellow soon-to-be-super-humans will undergo the medical procedures and training necessary to get them into Titan shape. Professor Collingwood (Tom Wilkinson) fearlessly leads them into battle, but you can probably guess that this review doesn’t end with “and then they all lived happily ever after…on Saturn.”

Of course not. Because messing around with the human genome, with evolution itself, is always, always, ALWAYS a cautionary tale. What normally takes millions of years should never be rushed through in a couple of days. It’s weird that scientists, the very people who patiently explained evolution to us, seem not to have internalized that lesson. So poor Joel is subjected to way more than he bargained for, and yeah it has some pretty scary repercussions for his family, but if you think about it, also for the whole of humanity.

Unfortunately, it doesn’t really seem as though anyone in the film has really thought about it. There’s a really interesting premise but the film fails in its identity. It doesn’t take enough risks, or ask the brave questions. And Sam Worthington is the blandest, most unremarkable actor ever – so much so that Sean wondered if he was possibly watching Joel Edgerton, who is the guy Sean is specifically blind to. But neither Worthington nor Schilling (dyed brunette, so she’s more believable as a doctor) are charming enough make us give a damn. Just about the only worthy thing in the whole movie is its location – beautiful Gran Canaria, Spain, which will make for a lovely holiday destination, and deserves to host nervier speculation on its picturesque island.
