Okay, this isn't a very funny review, except for Arjun's cartoon. LOL.
The Ananya-needing-help-in-economics part probably wasn't explained properly in the film. In the book, Chetan said that the teacher asked her some mathematical equation/representation/whatever of something related to economics and that she didn't know well as it wasn't exactly of importance/related to her subject, something like that, I don't remember that part well. She even says in class that I can explain the phenomenon properly but I only don't know the mathematical equation and the teacher makes fun of her. Then when she gets all emotional, Krissh explains that he knows this part well as he has studied it (being from a different stream than her) and can help her with Maths/Account/numbers related stuff, which she agrees to.
Regarding the sudden transformation and acceptance of his father, I always found it weird too about how his father changed suddenly and helped him get married and how they bonded again all of a sudden. It came across as the most unrealistic part of the novel, and didn't blend in with the rest of the story and character sketch, and guess what- it IS unreal. Chetan said in an interview recently that he made that part up of Krissh's reunion with his father and his father turning over a new leaf- it was his way to get over the negativity and hate he had for his father all these years cos of all that his Mom suffered, it was like a make believe happy ending closure to his story- truth is Chetan's mother separated from his father long back on Chetan's insistence, and he is on strictly cordial terms with his Dad, nothing more nothing less. No wonder it sticks out as a sore thumb in relation to the rest of the narrative.
