The film’s four directors/co-directors (Ron Clements, John Musker, Don Hall, and Chris Williams) are all Disney veterans with a specialty in films whose greatest strengths lay in movement (their collective resume includes The Emperor’s New Groove and Tarzan, for example).
So does Lin-Manuel Miranda, whose first new songs since Hamilton—co-written with longtime Disney composer Mark Mancina ( The Lion King , Tarzan ) and the Samoan-born bandleader Opetaia Foa’i—pepper the film and sometimes even have the energy to break through the accumulated cruft of decades of Disney boilerplate.
The film is the newest in a line of successful Disney cartoons: it follows "Mulan," "Hercules," "The Hunchback Of Notre Dame," "Pocahontas," "The Lion King," "Aladdin," "Beauty And The Beast," and, of course, the mother of them all, "The Little Mermaid."
The familiar ingredients—absent parents, unthreatening yet princely hero, perky but ditzy heroine, swarthy villain, cute sidekicks, hugs, lessons, and a CD's worth of forgettable pop tunes—have served Disney since 1989's The Little Mermaid.
"Revolutionary" and "Disney" are not words typically combined, I know, but the studio's adaptation of Tarzan must surely qualify: for it introduced a new technology that was the most important and amazing new development in 2-D animation since the introduction of CAPS with The Rescuers Down Under , nine years earlier (right, the "introduction" happened with one scene in The Little Mermaid , but that was more like a demo reel).
That's why Ariel survives in The Little Mermaid , the bulk of Aladdin only vaguely resembles "A Thousand and One Nights," The Hunchback of Notre Dame completely eviscerated Victor Hugo's attacks on the Catholic Church, and Hercules conveniently ignored the sexual appetites of the gods of Olympus.
