What a shame! (lots of spoilers included)

From about half way through, where the film should have been more and more exciting, it felt more and more like a drama about an abused wife.
There were gaps in the story, or at least I saw them as gaps.
There were story bits which didn't make much sense to me.
Why was that guy fired? There were only two hosts, nothing to make us at any point think there was a conspiracy going on reaching the NASA administration.
Were the radios at home special made? IF yes, by whom? If no, they waited for who knows how many years for communication to arrive...yet it was instantly available to them?
What was the vehicle of the aliens? If they were as mentioned, just traveling through signals, then where were they when they waited for the astronauts to come? Why didn't they just go to the targets on Earth and waited for them to go in orbit? If the alien was just signal, WTF was it doing with the physical form near the end?

The wife believed in the theory behind her husband way way too easily.

At least the ending was cool, not perfect and not well acted, but cool. I mean, the kids were bad and not too happy with Charlize's performance, but her husband did well.
I do wonder though, how was the death of her husband explained to the police.


With small changes here and there, the movie could have been much better, but it's not.
