I didn't love this film, but I was certainly entertained and I thought the concept was interesting. It'll be interesting to see the what the political climate looked like leading up to this. Perhaps in the sequels.

That aside, the film does do well with portraying technology of the future. It's realistic, at least at the time of the film's making, and isn't overly "in your face". One thing that comes to mind is Charlie's glasses, which featured pretty high resolution monitors showing the feed from his RC car... wirelessly!

The film was dark, but I think it did a good job of emphasizing key aspects of each scene. I thought the PoV from the RC car was a neat touch, giving it that sort of hand-held camera effect, but without the shakiness that normally comes with that.

[spoiler]I feel like there's a lot going on in this story that doesn't entirely add up. The entire story exists because Charlie opened up the house to the man. Anyone can debate the ethics in doing so or not doing so, but the point is that the entire plot exists because of this one action. I'm not sure how I feel about that. They tried to redeem it in the end, though, with the neighbors wanting in on it. Even that, however, wasn't well done. It was more of a "story's over now let's add a little more to fill out some time..." and they just, literally, sit there.[/spoiler]

[spoiler]I agree with the other comments that say the family needed a panic room. For such an event, the protection offered by the security system is mainly for looks. Granted, this was mentioned in the film briefly. Also, if the "polite leader" had any intention of keeping the family alive, why did he cut the power? Meh, I'll suspend disbelief for this one.[/spoiler]

This film wasn't good, and has a lot of plot holes. It felt as if they were stretching to get to 90 minutes for a feature-length film (they didn't by the way). I was entertained, but didn't really find much realism in the concept behind the film.
