don't waste time on "Knowing" its so boring it's actually frustrating to watch. It's also just a dumb story from an End of Days perspective.
The best part of the movie was the plane crash, that was cool. However I do even question that sequence of scenes. For example, if the plane was coming in for a landing, why all the explosions? Don't you need vaporized fuel to create an explosion? If the plane is coming in for a landing, it should pretty much have zero fuel to worry about.
Anyhow, other than that part of the movie, it's completely stupid.
