Just got back from the latest Nicholas Cage flick, and all in all, this one's a loser. It simply can't make up it's mind what kind of story it wants to tell. Is it an end-of-the world disaster movie? Is it about numerology? Is it about faith vs rationality? Is it a low budget horror film? Is it trying to rip off Childhood's End or Inconstant Moon?
There are a lot of ambitious stories that hit almost all of these themes. The successful ones are grounded in their characters. In Knowing, the actors are neither powerful enough in their performances nor generous enough in their characterizations to rise above the flaws in the story. Don't bother, even with Netflix.
