In the vein of films like Totoro, and in contrast to Mamoru Hosoda's previous Summer Wars, this film glides along without an epic struggle driving the story. Rather, the greatest moments are the depictions of family life and the picturesque sketches of Tokyo and the Japanese countryside.
The story begins with the start of the eponymous wolf children's parents' love, and progresses through births, deaths, moves, the first day of school, and their growth into adults. The story is almost too ordinary, but in its normality, its moments are universal. One can't help but stare in awe at the beauty of life as it happens, and be reminded of the beauty of one's own mundane yet special lives.
The art is also quite something. Tokyo's bustling life is reduced to warm glows of winter, and the Japanese farms and countryside is rendered beautifully whether it be in rain, sun, or snow.
Watch it. It's not of the same scale as Hosoda's previous Summer Wars or The Girl Who Leapt through Time, but it packs an emotional punch that surpasses either of them. You'll shed a few tears, and marvel at the beauty of the world and our lives.
