Every society needs a harbinger of change. In real life, they happen once in a generation. In cinema, they happen nearly every Friday. But, by harbinger of change we do not mean superheroes or their likes that fight, fly and preach their way to change. We are not looking at ‘Robin Hood’s or super cops. We are looking at the common man and people among them who showed courage to stand up for what they felt are right. We look at some of the best social reformers that have been created by Tamil cinema on screen.
