Cage is a practitioner of the Nouveau Shamanic school of acting but here he has dialled it down perhaps out of respect to the religious nature of the material, or perhaps he's saving the wild stuff for Con Air 2: This Time it's Biblical.
Left Behind is essentially a bad disaster movie, but I swear to God I've seen worse movies this year, and worse Nicolas Cage movies at that. I can't in good faith tell you to see it, but I'd be lying if I told you I didn't enjoy it.
The basic premise of the film could have made for an engaging and far-out watch. The very concept of the Rapture could have been depicted with power and mystery, but instead the opposite is achieved in a film that just looks slapdash.
Overt Christian messages and Cage's omnipresence are not the only reasons why Left Behind is a terrible movie. And yes, it's indeed terrible-god-awful, a less interesting, more convoluted version of the original Left Behind.
This new film is a watered-down and somewhat changed version of the earlier movie with a bigger budget and not much else. There is barely enough undercooked scriptural theology to critique in the vacuous writing and painful acting.
