Its not your fault if you don't know anything about Salman's Box office performance in 1990s.
Salman khan gave an excellent opener and hit in the form of Baaghi (19990)
Saajan - Bumper (Blockbuster)
Sanam Bewafa - Atleast Superhit
Kurbaan - Good opener maybe a hit after update.
He was bad from 1992-1994 in terms of initials
But from Karan arjun his most films opened to big occupancy.
You're calling his peak 1998-1999 as Good when he outdone everyone in 1999. As i said no one was clear no.1
