OK, lets have some reasonable counterpoint.
This is a poor message. Is it because it's dark and sad? No. It's because it's about fear and furthermore, bullshit. My favorite times when I was a kid were spent wandering around, exploring, having adventures by my damn self. If my loved ones hadn't left me alone, I never would have had that, and I wouldn't be as independent as I am. Not that it would have been a bad thing to always have people around, and not that a coupla bad things didn't happen. I got in a few fights, stole a few things from stores, got robbed once or twice. But it was ok.
It really bothers me when I see the news full of kidnappings and murders and muggings, and I see parents putting their kids on the swings in bicycle helmets and moms feeling like they have to watch their kids every second. This is wrong.
Compare the frequency of kidnappings and violent crimes to the frequency with which people go out, alone, on the street, in nature, all over the place, and you'll realize that you shouldn't be afraid of things happening to the people you love. You SHOULD NOT feel you have to be near them all the time, because you'll stifle all the vim out of them if you do. You SHOULD help the people you love avoid taking silly risks like walking down dark alleys at night to take a piss. Take home message: don't be afraid, just be smart (and it never hurts to be fast).
The movie was somewhat touching and very well drawn, although it lacked plot. I just violently disagree with your message.
