Abhishek Bachchan is an actor and son of Amitabh Bachchan.
Today he is very well known as the son of the great actor Amitabh Bachchan. Though he has been in this industry of films since many years, tha fame and popularity he has gained is majorly due to his father's name behind him.
He has worked in many films till date and the only good ones he was able to manage as far as I think are the Dhoom series and Guru and LoC Kargil. Rest of his films were majorly a flop. For eg-: - Bol Bachchan.
His acting skills are quite weak or maybe it could be the case that people expect so much more from him thinking he is the son of Amitabh Bachchan.
As far as personality is concerned, he doesn't have a personality which you would seek in a actor. No physique, no acting skills nothing.
Mass popularity is solely due to his father being Amitabh Bachchan and some of it due to his work in films Guru and Dhoom.
Overall he is an average actor from whom you can't expect an outstanding role. An outstanding role play from him comes once in a blue moon.
