Director Andrew Stanton ("Finding Nemo," "WALL-E") gives us a remarkable story that celebrates old cinema (the silent movie, the musical) while delivering a message about the need to protect the planet (and our health) as flashy technology takes over.
Pixar is known for making us care about fictional creatures and objects, but with "WALL-E," that connection to the characters, the sense that they're living beings, is so intertwined with our experience of watching that you have to remind yourself it's just a story.
And that's the best kind of storytelling.
