Yeah .....agree. As you said, I would like to see a modern day version of that. Was the postman close to such a script....?
I don’t think so. I can’t think of a really good comparable SHTF movie. The Road is too grim, just kill yourself already. Mad Max is silly, they are out of ammo but have plenty of nitro-burning monster trucks? Really? I can’t think of a really good contemporary SHTF. Book of Eli is good but mystical (blind man who shoots arrows etc.)
