Attention to detail

The attention to detail in this movie is mind blowing.

1. The writing pad that Regina uses is of a 'Tiger' brand.

2. Although not perfect, the interplay of the narratives have very few continuity errors.

3. Every dialogue and every event has got something or the other to do with the story or characters. Eg. Munna tells Balu while drinking (Chapter 5 : Ka) that he doesn't want marijuana, and that he would lose control of himself. That's what happens in the end.
