Oh where to start. Such an interesting concept with so little thought as to how anything would make sense.
1. Earth is dead and yet all you see are pristine mountain ranges, picturesque schools and multi million dollar homes.
2. There's little to no background information on the main characters.
3. All if a sudden you can just hold your breath for 40 minutes? Why and how?
4. All of a sudden participants are trying to murder people. Why?
5. All of a sudden you go into one night of surgery and you have an entirely new epidermis, facial structure, wings, no ears and you lose your ability to talk? Why? Oh and also at the end we can see you no longer have genetalia so how is that helpful to keep the human race alive? And why all of sudden were their fingers joined and what are those tentacles that somehow have super power strength?
6. Oh and not to mention somehow your wife is able to just freely walk around a Military base undetected?
7. And let's not forget that somehow you manage to fly to Saturns moon in the span of a few days and you are alone, flying off of thousand foot cliffs, naked for some reason, unable to communicate with anyone or procreate and you are the future of the human race? Oh also the irony of it all, you arent even human!
