"For good measure, it gives the last word to a snooty food critic (Peter O'Toole) who sees the light and argues that the best role a reviewer can play is to champion the new; hailing those unsung heroes who are trying something different, regardless of their background, colour, creed or species."
This is taken from the Guardian's review of the film Ratatouille (which I loved by the way). I think it sums it up so nicely.
I loved the colors of the film - not the harsh bright ones of earlier Pixar, but lovely tones of blue and red and copper and green, with images of Paris so lovely and romantic. And the rat is amazing-even his colour is great. Visually (and not only) inspiring.
