Interesting concept but not carried out well. Using climate change and pollution as the reason to modify humans for a distant moon with no infrastructure on it didn’t make any sense. If the world was ending because it was going to implode or something then that would make more sense. Otherwise, why not just modify humans to survive in the new climate and pollution on earth? And what is the goal exactly of sending him to titan, what’s he going to eat? For all we know he still has the same diet, as he was just eating a peanut butter and jelly sandwich while transitioning. Who is he going to procreate with?
The whole movie they kept saying they were doing this for their kids. I would’ve liked to have seen some elaboration on that... like 300 years later they now have a thriving colony or something the same population as earth. With a program to transition humans into titans while they are traveling in space.
