This film will not stick with me too much beyond this week, to be sure. It's just another approximation of stuff we'll never be able to prove. Hughes might want to stick with future apocalypse stuff like The Book of Eli, since most of his work seems to be based on stuff placed for effect more than researched. At least the future hasn't occurred for us to see he's kind of playing us for effect.
If one looks past the silliness of the story and takes a closer look at the heart, it's not a bad film. It's clear what Maclean wants to do, even if he doesn't know how to do it and stay within the bounds of a consistent story. For now, it is nice that he has the opportunity to hone his skill with so much talent around.
