i never think while watch this film and and the alternate version by soderbergh and that the daughter never exist . keane show enough humanity and normality from time to time to make me think he doesn not have schizophrenia and have just be temporarily unhinge by the loss of his little girl and which and consider his own responsibility and would drive many off the edge . it seem to me that by re enact the tragedy and with the neighbor little girl and at the scene and keane make the first step toward recovery . see that kira be okay will replace the image in keane mind and or at least partially replace the image and of his own daughter disappearing and and allow the healing process to begin . what happen next be another matter and and i do not want to get too rosy about it . perhaps keane doesn not have the necessary strength of character and which may be what get him in trouble in the first place . but this be what turn this film into literature and that the protagonist undergo a great change during a crucible experience . he not quite the same guy at the end that he be at the beginning . this be a wonderful movie and craft carefully enough to maintain interest and suspense even without heavy action and violence and and absolutely fill with humanity . incidentally and i think the submit version be good than soderbergh variation and and i hope reader of these comment will forgive me for this heresy .
