'The Polar Express' (2004)
A wondrously imaginative, diverse, and spirited allegory of childhood and the arduousness of adulthood.

Sidney and Dre can attribute their lifelong friendship and the launch of their careers to one single childhood instant... witnessing the birth of hip-hop on a New York street corner. Now some 15 years later, she is a revered music critic at a national magazine and he is a successful, though unfulfilled, hip-hop record company executive. Both come to realize that their true life passions will only be fulfilled by remembering what they learned that day on the corner.
A wondrously imaginative, diverse, and spirited allegory of childhood and the arduousness of adulthood.
In addition to the cast being delightfully diverse this time around, the film was just loosely-plotted and action-packed enough to keep a casual fan like myself entertained. While I do agree that the writing of Cole left much to be desired for an original character thrust into a preconceived universe, none of the characters seemed particularly fleshed out in terms of personality; however, I think that's to be expected when you're watching a film literally inspired by a video game.
Two movies that do a fantastic job in conveying the ongoing struggle for racial justice are Selma (2014) and Just Mercy (2019).
