Two sisters and the off-screen adventures of one of them. The music is lovely, there's a lot of potential, but it's hard to tell what's happening on the first viewing. While there's plenty of great cinematography, retrospective storytelling really needs more than snippets of dialogue to to be properly effective. The sisters don't age, the shots of the calendar don't direct your eye to the important details well enough, and the most interesting parts of the story happen outside the film. It's not a particularly exciting story, but there's plenty to keep your interest if you pay close attention (though the most entertaining part of the film is the nervous boyfriend at the end). We forgive a lot for presentation though, and the film looks very nice. Black and white with overlays and a great score give it a great artistic look which ultimately saves the film.
