It was after Varun and Alia that the whole nepotism came, Abhishek is a clear example where he is a decent actor and was offered multiple roles but he rejected so many of them and his script sense is screwed.
I don't think he was ever invested in acting and he never put in the effort to look a part. He did roles where it was more of a sleep through than to put in that effort. He should have stuck to business and not acting. I mean Amitabh at 60s and 70s changes his looks, be it Paa, Black, Cheeni Kum, Piku even for that matter KBC the way he talks, walks you can see that he clearly loves his job, hell even the green shoes he wore at KBC became a style statement.
Nepotism gives you many chances and great scripts but Abhishek rejected a whole lot of th and chose medicore ones , and as much as Alia or Ranbir are very very average actors at best atleast they did choose some great scripts at least till a couple of years back
