Disneynature films are not for the faint of heart. The entertaining and educational series has consistently placed a premium on absolute veracity – even when it comes with a very palatable and painful cost. The last Disneynature film, Chimpanzee, was built almost entirely on tragedy, as it centered on a young chimp (adorably named Oscar) who struggled to survive after the sudden death of his mother. The film’s very plotline was centered around death – a natural and normal death, but death nonetheless – and the entire film was a steady mix of the sad and the joyful (Oscar is eventually taken under the furry arm of an unexpected surrogate parent – another male chimp). Back in 2011, death also hung thick over African Cats, with one plotline following a cheetah mom who eventually loses two of her five cubs to hunting hyenas, and another chronicling an aging lioness who must abandon her own cub to her pride after getting injured and feeling compelled to sneak off to die alone. Yet, for all the tears that Disneynature aficionados are seemingly doomed to shed (and, man, are you doomed to shed them), the films are also fiercely satisfying in ways that are hard to replicate in the majority of purely fictional, human-based settings. Yes, you’re going to cry, but damn if it’s not worth it. The latest Disneynature film, Bears, is no different than its predecessors – in fact, it’s the best of an already very fine bunch.
