War Of The Worlds: The Nine Questions (Spoiler Alert)

Okay. I saw War Of The Worlds opening weekend. It was a pretty good summer movie... if you don't mind movies with logical flaws. As I watched the movie, I saw many things that brought questions to my mind. I dare you, if you can, to answer THE NINE QUESTIONS! (I'm warning you, if you haven't seen the movie, you might not want to read any further. I tried to be as vague as possible, but the questions might ruin it for you anyway.)

1. How come the video camera worked when it was clear that ALL technology had stopped functioning (cars, cells phones, TV, etc.)?
2. How come the river was full of dead bodies? I thought the aliens were VAPORIZING people? It looked more like it was logging season.
3. How come the van didn't get destroyed in the plane crash? I know they're safe, but c'mon.
4. Why was there a path for the van to drive through?
5. Tim Robbins' character had a weird accent when we first meet him. He sounded like an idiot. Moments later he loses the accent. Where did the accent go?
6. How come the kids' mom, her husband and parents didn't leave their living room? Apparently, everyone else ran for their lives while they remained oblivious to the mass destruction around them.
7. How come Tom's son didn't die? We all know that he should have been blown up or fried in that explosion. Lamest. Movie. Ending. Ever.
8. How come the aliens were vaporizing people, but then they were eating them later? Don't use the "they needed to use them for their food supply" excuse. They would have been herding them like cattle from the get-go.
9. Why were the kids so stupid? Examples: Boy sees person get vaporized. "What just happened?" "Did they come from Europe?"
