Saw the film. Honestly, the religious element killed the entire films potential impact.
For one reason, religion is the ultimate Deus Ex Machina, and Deus Ex Machinas suck in these type of stories.
Two, alot of people are saying "Ignore the religon, be all cerebal and shit and make up your own opinion on justifying how my obscure observations make this film about religion being bad". No douchebarf, what's on the screen is simple theistic afterbirth. Being existential and shit doesn't make the movie any better.
What's worse is that religion is using the post-apoc franchises as a vehicle to pull in the young with justification of violence and fucking on a nitro truck. It's basically a representation of the Alabama/Georgia/South Carolina trailer park mentality.
Post apoc is so deep, complex, interesting, and emotionally challenging because it's a scenario with no "Right" answers, and every action a person does is just one invented scenario with consequences. This movie jizzez on that concept.
