SPOILERS:
I wish that it would’ve ended with the bunker exploding and her finding out that the air isn’t poisonous.
How would you explain what’s her name from Silicon Valley showing up looking all fried, then? Or for that matter, Emmett kind-of-sort-of witnessing the disaster? There needed to be something going on outside of John Goodman’s head; otherwise it’s just another maniac with a bunker movie.
Let me clarify, I still want for her to have driven away and heard the radio message and then go to the city to help. I would’ve preferred that they left it open to whether or not it was a foreign invasion or an alien invasion. Just cut out the whole rest of the final segment with the battle. I thought it was well done the way it was, but just unnecessary.
