In the sovereign state of India where there is freedom of speech, any one can talk any thing. Just now read a review on Sivaji, I could only pity such people - what all they have to do for money.
According to me, the movie was a decent watch. Also it is probably the biggest commercial hit in recent times. The producers are happy, actors are happy, distributors are happy, fans are happy - the movie has raked in multiple times of what has been invested. It is not often a regional language movie of India gets into the U.K. top 10....many more of such oft-repeated success stories.
There is no point analyzing successes.
