Movie was a disappointment, first part while slow was decent, although the Christianity focus was a bit forced. The ending though was abrupt, characters disappear and we get a whole new character during credits with an idea that hasn't been mentioned before.
Would have been much more interesting if they had gone down the whole path of how someone like John survives in our modern world, or dig into why he's changing.
If your bored go ahead and watch it, just don't expect anything like the original.
