Our airwaves are saturated with unbelievably effective pro-charter ads (from Charters Work).
This one in particular is riveting; I watch it all the way through every time it comes on. It's like a little mini-narrative -- not so much on first viewing, but on repeats. You get to know the kids; you know the sequence you're going to see them in; and pretty soon you start to feel a build-up of dread each time you watch, knowing what's coming next, which is that the beautiful children will disappear one-by-one, and the little boy looking at you over the top of his spectacles will be the first to go.
It's like a terrifying work of dystopian sci fi, for pete's sake.
Or one of those horrifying news clips like the Challenger explosion that you watch every time it's shown, hoping the ending will be different this time.
Watch this ad ten times in ten days and you'll see what I mean.
