Children's animated films, like just about everything else these days, are mostly created by a couple of mega-corporations. Some days it seems like the only animations out there are digitally rendered, hyperactive "Pix-ney" flicks filled with pop-culture wisecracks and supported by a $100 million budget. There are plenty of fun films that fall within that category, but parents who think their kids deserve variety in their cinematic diet will be pleased to find there are other options this summer.
