Stars and planets constantly move, but even a thousand years ago they looked the same from earth, inspiring countless mythologies to adopt similar symbols for love, loss, life, and time. From the perspective of those stars, humans must appear quite cyclical folk, making the same mistakes and chasing the same dreams no matter the millennia. “The Fountain” is a story of love and loss as from the perspective of those stars. Unfortunately, it seems like the stars spent less time reading Joseph Campbell (author of the mythologist’s bible, “The Hero with a Thousand Faces”) than they spent watching “The Notebook.” It’s as mystifyingly impersonal as you’d imagine of a rom-com (hold the com) from Icarus’ point of view. But where it really burns up is how discernible it all is once you sweep up the mythic pretension of a three thousand year story and put what’s left back on its cramped, 96-minute shelf.
