First of all the positives. There is no denying the fact that technically, the movie has been made well. The story, the acting, the editing, the photography, the locations are all wonderful to say the least.
Now for the negatives. The movie is more like a documentary highlighting only the worst (though requiring addressability) issues. It seems the director has tried to derive vicious pleasure in every bit. The movie shows the life in slums in Mumbai, but does not capture any positives about mumbai whether it be the hardworking nature or the never say doe spirit. Nor has it made an attempt to capture the problems faced and the reasons for the situation.
The feeling I got while watching the movie was the same as you get while watching a foreigner click ptctures of beggars and poor people at stations/ public places.Can watch though you will not miss if you do not.
