Some good acting marred by the wrongness of the central thesis. it's basically the opposite of 'Eternal Sunshine'. What we want to do is forget. Move on with our lives. Of course it might be nice to see the whole thing after we're dead, but it's important not to live in the past.
Although it has serious flaws on its narrative, this film is remarkable for both its cinematography, its cast and the delicacy of its direction. The story, nonetheless, is seriously damaged by certain nonsensical points and a general feeling of unfulfillment. Worth watching, though.
