It all started with Om Shanti OM in 2007
11 years has been passed but no NonKhan movie has ever emerged HGOTY.
Beware Sanju the big daddy of box office is coming, I think it will be 12+ with Either TOH or Zero emerging Hgoty.
Though most chances are there it will be Toh but with a massy commercial potboiler from the maestro ALR chances of zero also can't be ruled out completely.
Either way I feel a Khan movie will become Hgoty and will extend the domination of the Three biggest names of the country.
