Tonight’s episode of Once Upon a Time features the show’s take on the popular Disney animated film The Little Mermaid. Though promotion and buzz do not always translate into higher ratings, ABC has put a lot of effort into spreading the word about this episode. Last week OUAT rose to a 2.2 among adults 18-49, from the prior week’s 2.1, against the World Series. Will the addition of Ariel be a A Whole New (Ratings) World for the show whose numbers have, compared to its prior seasons, sunk Under the Sea this fall? Make your predictions!
