I will give zero stars as rating.
This serial just a wish fulfilment of an insane person.
The character of karna is changed complete to a saint which is utterly false.
Do the makers don't feel any shame in twisting the stories as they want.
Where are those organisations and politician who call themselves sanatani, when these types of twisted stories are taught to the new generation.
The coming generation will complete be unware of what is fiction and what is real.
Maybe in a few decades kaurav will became good and pandaw will became villains.
Some people connect karn's live with casteism.
But let me tell you even if he was known as a sut putra he was demigod by blood, birth and boon.
If he was real son of adhirath and Radha then he will never be able to become that strong even after being taught by parshuram. Just like a normal person can't match a demigod.
Therefore Karn' s life can't represent harsh life of low cast (sut putra) at all.
