The acting is very amateur... He's overdoing and he's clumsy (taking pictures as he walk, c'mon guys!) She is pretty much only asking rhetorical questions and lots of "what ifs". The script is made by students I guess... the most lame Adam and Eva I've seen.
What does an average American couple do when the rapture strikes? They "upgrade". They get two SUVs. They "supersize" this and that.

I find this more terrifying than the end of the world.
