Abhishek Bachchan?? His dad is good, but AB junior is at most a poor clone of his dad getting undue media hype.
Aamir Khan knows how to act and direct, and SRK showed his histrionic skills in only two movies-- 'Chak de! India' and 'Swades'. I can't vouch for the same in the case of Salman Khan.
But yeah, Dutt and Khanna have done well in some films. Warsi is only excellent as Circuit (nothing else)!
