There are always adversities in life, it is important to build resilience and growth mindset in kids to stay strong during difficult times in life. These movies are great stories teaching kids life lessons and coping skills, good for kids of all ages, from preschool to elementary school to high school.
Spirit: Stallion of the Cimarron is an animation from Dreamworks, a story about a horse. Well, it's cute and all that but it's certainly not in the caliber of Shrek or other hits from Dreamworks. The storyline lacked depth and as good as Matt Damon may be, riding on his name along doesn't produce a hit. May be worth watching with kids who like westerns.
