In the L.A. Weekly, two staffers take decidely different approaches to the presence of children in film:  looking back at the history and the development of the on-screen child, from The 400 Blows to Little Miss Sunshine, Ella Taylor notes a reflection in contemporary cinema of our curious blend of overprotectiveness and overpermissiveness, and wonders why Hollywood has, unlike other countries, had such great difficulty promoting the development of a great director who makes films primarly for kids.  In the same issue, John Anderson, taking a very different tack, notes that increasingly, children have a shorter and shorter life expectancy -- on screen, at least.  Citing a recent crop of movies from Pan's Labyrinth and Planet Terror to 1408 and Lonely Hearts, Anderson points out that it's becoming even more dangerous to be a child on screen than it is to be an adorable puppy or a wise-cracking black sidekick.
