In the successful wake of Who Framed Roger Rabbit, which caused a resurge of interest in animation, Disney had a chance to re-emerge as a great animation power. A bad movie would have probably killed animation, leaving Roger as a flash-in-the-pan and cartoons would have returned to the status as purely kiddie entertainment. Fortunately, Disney (and animation in general) was reborn with The Little Mermaid, a film which appropriately enough returned Disney to their original tradition of remaking fairy tales.
The Little Mermaid follows the fortunes of Ariel, a misfit mermaid princess with an obsession for humanity. When she falls in love with a prince, she trades her voice for legs in order to pursue her love. She has only three days to make the prince love her in return.
Along the way, she is aided by a childlike fish, a stern but softhearted crab (Sebastian has to be the best character in the film) and a screwball seagull. The movie features a large variety of likeable characters, as well as a quite effective (and visually arresting) villain.
A good, solid (but not deep) teenybopper romance, The Little Mermaid also features some of the most memorable songs of any Disney feature. They were written by the hit songwriting team of Howard Ashman and Alan Menken, still glowing from their successful musical, Little Shop of Horrors. (They went on to write songs for Beauty and the Beast and Aladdin.)
For sheer light-hearted musical fun, the Little Mermaid has plenty of appeal and laughs.
(And people who enjoy trying to find hidden naughtiness in Disney flicks can have fun arguing whether the bulging wrinkle at the front of the priest's robe at the beginning of the wedding ceremony is suspicious or not.)
