Movie anyone?

Just rented Knowing with Nicolas Cage. Great Rental and I recommend it to anyone.
Not a Blockbuster or anything of the sort, but good enough for a nice evening under the Air Conditioner and in front of the Tube.
Superb Special Effects and a Story line that keeps you fixated to the main characters.
I don't want to spoil it but there are some things I can't grasp.
How did the Aliens know what is coming? Why did they wait until the last minute?
Why Noah's approach? Probably only because it makes better theater, but still.
If you're like me and you place yourself into the character, you'll figure out alot of the plot before it happens, however it still makes for an interesting chain of events and if anything else gives you a sense of satisfaction on figuring it all out.
My links aren't working in the posts, I'm still figuring this all out...help me...
but you can click on the "Movie Anyone" Title for the Webpage.

Knowing: 8 out of 10 stars.
