First let me tell you that I'm biased and here to give positive review.
Now I'm going to state the reasons -
1. There is two types of knowledge -
(I) Vidya (self knowledge)
(II) Avidya (worldly or physical knowledge)
The indian education system in based on Avidya,
no such reform has been taken to direct the teaching towards Vidya, the result is crimes on inhuman nature.
2. Good good Bad bad - no one escaped the death - this realisation can lead to two kinds one is be good and beautiful bad. Afterall we are all going to die why not do bad and enjoy pleasure, this leads to a immoral life . This is shown in the film.
3. People's perception of horror and enjoyment are two sides on a coin, we are animal - the lion in the jungle, the cat on the sofa and you are no different. We are so apart from the jungle we do not thing we are animals. Only a few very few has wisdom, because no one is not chasing it. This films shows what usually happens, it is not a discreet event.
4. A film is a good film if you can not distinguish if it they are acting or is it really happening. People want to see unreal things and even if they see reality then certainly say it's a film. It is not !
