I teach high school Spanish, so I am sure to be biased. But this movie Rocks! As a Spanish teacher, there is no better resource to use in my classes than the movies from this series, which also includes La Leyenda de la Nahuala.
The improvements in animation, story, and humor in between this movie and the Nahuala are great! They really nailed the story of the Llorona. I laughed out loud, was decently scared, and started to tear up. And this is all when I watched it alone. My Spanish classes love it! It showcases Mexican culture, including indigenous and Spanish influences, and integrates it seamlessly into the storyline. It's funny, scary, and heartfelt. Perfect for celebrating Dia de los Muertos (Day of the Dead).
