Karishma Kapoor can always play the dutiful sister to Kareena Kapoor. Wished it was the same for Karishma, had Kareena stepped forward to maybe promoting ‘Dangerous Ishq’ then the film might have worked for Karishma. But then again, Kareena is damn busy. Karishma says that ‘Heroine’ will be the best film that Kareena has done so far. So far, the trailer and promos look really good, so let’s hope it doesn’t disappoint.
