I don’t have a movie review at the ready, but I think something I wrote in my review of Inside Out would be relevant here:
Our lives are constantly marked by the reality of being in statu viae — “on the way”… In this life, we are never at home in the sense of a place of final rest. Our lives are shaped continually by hellos and goodbyes of various kinds — with other people, with places, and with places within.
While this is true of all people without exception, we sometimes feel isolated, believing that, while we can celebrate the hellos together, we cannot grieve the losses together (even with those we love and who love us). Yet sadness expressed can be isolation overcome. Paradoxically, grief shared can become sadness transformed and touched by joy, because our greatest need as humans is not to experience unqualified and perpetual joy, but to experience life in communion with others.
