This film was amazing. No One Killed Jessica is touching and it has real meaning.
The closest North American peer that comes to mind would be Milk (which I also recommend checking out).
By focusing on the case of the murder of Jessica Lall, it tells an important story of the corruption and hypocrisy of the courts in India but speaks to each legal system in the world.
The soundtrack is bit of a let down and a mixed bag, because at times it was just so distractingly overwhelming soundtrack that it was way too much for the scene while other times songs so enjoyable and addictive that you pretty much distracted from again from the point of the scene.
This combined with a rushed pace for the second half of the film makes me want to read any books or memoirs or any other source of the scandal rather then watch it over again. Nevertheless, it is an amazing movie and you need to go see it.
