If Zoya had a certain vision of the movie that the newcomers couldn't fulfil she shouldn't have casted them...simple as that...so, there had been a reason why she thought it would be a good idea to cast six young people of whom only one already had acting experience in front of movie cameras and one a career as a singer.
When all those preparations she allegedly let the newcomers do and she still wasn't able to bring out of them what she wanted, then it was just a false decision she made.
Maybe a more Indian youthful movie more being rooted in Indian life and n o t transporting a Western 'thing' into a Westernised Hill station and making the youngsters thinking like in a Western movie... well, you get it, right?
