Why is this insecurity from a film?

Kerala Assembly LoP and Congress leader VD Satheesan writes a letter to the Election Commission of India, on Doordarshan screening 'The Kerala Story' movie.

The letter reads "...As you are aware, Kerala Story is a propaganda film based on extremely false premises and attempts to paint a bleak picture of the people of the state...It is also in violation of model poll conduct, which forbids any effort to divide society on religious lines. In light of these contentions, I request your good self to direct Doordarshan to withdraw from its decision"
