No one language can ever dominate film industry in India.Its virtually impossible for hindi industry to come to south just as south industry cannot go to north.Both cultures are different in lots of ways.Plus telugu and tamil industries are technically much better and also massive by any standards.They are not just any regional movie industry. There is more money in hyderabad than in hindi industry.Talent wise tamilians are unbeatable anywhere in the world.Hindi actors are good in looks.So its very diverse and each is good in its own way.
