You would be hard pressed to find a more nonsensical plot, maybe if you found some demented 7 year olds, loaded them up with sugar and spun them around very fast.
PREMISE (and I use that loosely)
The world is dying because all plants are extinct because of evil virus humanity
So there is no oxygen (OH NO)
(let's ignore that a huge amount of oxygen comes from the sea, ok, just a movie, just because they use scientificulation wordablage durn't mean it needs to make sense)
People survive on factory produced artificial oxygen in cannisters (but huh?)
The top scientists, none seemingly very bright, decide that with the last two power modules they would send the most useless, teary eyed, easily baffled, emo, maintenance worker and his drinking buddy to umm, stuff, and other stuff, and, well, they don't really give him a clear mission or goals, more a sort of, hey, you go, good luck and all, the dying Earth is, well, we have no expectations.
Now if you think I am being too harsh, one of two things are happening.
1. I am not being harsh enough, you just don't get it.
2. You have suffered a massive cranial injury and have decided beige paint tastes the best and licking windows is quality entertainment.
But who am I to judge?
