On one side I am extremely disappointed with Zee creatives for not going to the southern part of India and instead choosing Non Indians. It is a dishonor.
On another side which is actually from Zee's TRP point of view and also based on the popularity of local channels. The regional channels are widely watched in this part so the TRPs are always low for Hindi channels whereas Pakistan watches more Indian television than their own. There are also these types of singing contests in all the regional channels so most prefer to go for that.
I still don't think it is justified to ignore such a major part of India and going out of the country for talent search. Also selection based on zones was itself a cheap tactic. I wish we could voice our disagreement through a proper channel.
