The first one does have a bit of a love triangle, which has been treated very differently. Both have been made keeping the commercial prospects in mind. I can define the film as an emotional thriller, in which people will find a totally different Salman Khan. The film will also find appeal among the family audiences. Both Rani Mukherji and Preity Zinta have equally strong roles in it.
People normally tend to associate the word thriller with murder mystery.
But our definition of a thriller is different. The audiences will go and watch the film with a certain presumption but they will be in for a big surprise when they see it. I am sure the audience will be kept guessing about every single frame in the film from the first to the last one. That's not true. Doosri Dulhan was a tragic film and it was a different subject.
