I agree with Hitesh.
It's owing to the fast pace and focus of the movie, that relationships, other than Amitabh and Abhishek's, are not explored. Usually movies like The Godfather and the likes have this pace and approach.
I liked the movie and I think the sequel to this, is when you'll see the stress on Aish's character. I'm not sure why it is not understood that it's a part by part tale. The way Abhishek's character was wrapped up, and the note at which Ash was left, wasn't the no frills, no nonsense approach of the film clear?
And yet, the gradual shift of Ash's interest from business to people was visible. It seemed she was being imparted knowledge from Abhishek. Abhishek explaining her his own understanding of profits....
If the screenplay or the story line is being discussed, liking could differ with people. Errors? hmm...nah - no glaring ones. And if one is looking for errors......then well! ;)
