Pixar is deservedly the poster-child of the rendered animation world and this is undoubtedly the best for its time. The sound, textures, lighting, character, prop and scene design are outstanding in Pixar's oeuvre.
As for the writing, there's quite a bit of tongue-in-cheek stereotyping of the human component but the majority of the film correctly focuses on the relationship between EVE and WALL·E and gives the sense that although both the product of humans they have much more to offer the satellite-clouded toxified remains of Earth than the people.
The child-like innocence of WALL·E immediately garners the audience's sympathy and support as does his demonstration of his raison d'etre to EVE concluding with the endearing "Ta-da!" The love story is incredibly moving, particularly so when EVE goes into stasis after acquiring a biological specimen. WALL·E's tenacity and determination to take her to his favourite spots in the hope of eliciting a response from her was crushingly reminiscent of when a loved one is in a coma. This quite choked me up. And this is barely 1/3 of the way through. The film is so enthralling that it seems to pack more into less time. The dance sequence between the two love-struck robots was very well executed and scored (the music throughout the film is superb) and the disturbed cloud of ice crystals gives a great hook for the very funny Pixar short BURN·E.
This film is filled to the brim with heart, perhaps just a little more than it needed but it's forgivable. To squeeze so much emotional range out of the main characters given their design showed a thoughtful process that flows into every niche of the film. The detail and quality of every aspect of this film is breathtaking. For families, for children and adult children this film is a keeper.
