Herione!!!

I was seeing some old movies, mid 80's movies to be precise. I found that the heroines had a significant role to play like a female reporter or some role where they have some worth not like some college student like shown today. Their roles carried some importance there were some catfights between the heroine & a gal in the villan group(Silk mostly....) But nowadays most heroines role is limited to dance for some item numbers & come as glamor dolls..

Even glamor gals of the old films had some roles like gangster gals etc..

Where are we going?
Why don't we portray women properly in movies nowadays?
Will a movie like Erin Brokovitch ever made in Tamil film industry?
