Although the movie might not have the best direction or not one of the best laid picture it still has a lot of good things. If you have visited India (where it has been primarily filmed) and especially Kolkotta city you would see the realistic nature of movie. It depicts the day to day life of a person below the poverty line. It also highlights the morality of foreigners and NGO's who are trying to help the needy. Very often they have to face resistance from local authorities who either want to exploit the masses or think the foreigners are trying to religiously exploit them. In nut shell I liked the movie.
