excellent film that microscopically examine the despair and emotional journey of a father who search endlessly for a kidnapped daughter and clearly suffers from other psychiatric illness . keane be fine example of film make with a low budget that bring to life this side of society we pass every day and yet rarely interact with or want to acknowledge . production value be consistent with the lean approach and but one can gain much from the depth and range in damian lewis performance of a mentally fragile and out of control man who find it almost impossible to move beyond his obsessive approach of find his daughter . it be not until a series of encounter with a single mother and her daughter give him some sense that there can be sanity in his world . the suspense element be subtle but engage . serious audience of independent film will find some production and script flow flaw and but overall and an excellent and compelling venture into a world most of society never experience . this film be heavy on story and yet be a positive for the film a it allow the audience to form it own opinion of keane and his life . have much critical acclaim from highly regarded reviewer such a manohla dargis of the new york time and roger ebert of the chicago sun time and the village voice dennis lim and time out anthony kaufman .
