A landmark achievement in computer animation, Dinosaur (2000) is one of the most expensive films ever made by Disney and a visual tour de force, although it suffers from a by-the-numbers plot line reminiscent of a Screenwriting 101 class. After a powerful opening sequence featuring the dizzying flight of a pterodactyl and a meteor shower probably too intense for the film's intended audience of young children, Dinosaur lumbers into familiar territory with a programmed story in which every beat is telegraphed far in advance. Mindless villains that don't exactly ramp up the tension and less than inspired vocal performances from leads Julianna Margulies and D.B. Sweeney, neither of whom has a particularly memorable or unique voice, add little to the proceedings. Regardless of the film's script problems, however, Dinosaur is a feast for the eyes; it represents, along with its equally successful box office competitor Chicken Run (2000), a year of major advances in the overall quality of film animation.
