In Andhra Pradesh and possibly some of the other states in South India, there is a strange concept of being a fan of an entire family.
For example, I know many people who are fans of Chiranjeevi and his entire family. So, these people will be fans of anyone who comes from Chiranjeevi's family. Then there is NTR's family. Many people are fans of the entire NTR family.
I can understand people being fans of a particular person. You like his/her looks or acting or demeanor or whatever and you adulate him/her. But liking the whole family by virtue of the relationship really beats me.
And Chiranjeevi family fans, by definition are against NTR family fans! So you have people getting into wars around the release dates of films featuring any member of the families. All the Chiranjeevi family fans will try to make sure that any film that has Chiranjeevi, Pavan Kalyan, Allu Arjun etc. is a huge hit while NTR family fans will ridicule everything about the film.
Similarly whenever any film featuring Balakrishna, Junior NTR (another first from Tollywood!) etc. is released the NTR family fans will try to ensure its commercial success while the Chiranjeevi family fans will go about denigrating everything about it.
I know some people from both the groups and don't miss an opportunity to tease them about this!
