Not to make this any deeper but those two got the time and space to improve their skills. If there was no nepotism, they wouldn't even have recieved the roles they did so they could improve, ya know what I'm trying to say? Others don't get the same opportunities as them at the start of their career, like Kangana or someone like that.Alia and ranbir are two products of nepotism that are deserving of a career as they are talented.
