History repeats itself - from Langda Tyagi to Rehman Dakait

Aren't there nth examples in the filmindustry/-ies for certain characters not being so-called 'lead characters' to make a lasting impact?

Fine for all those actors and actresses who get a role that let them shine

From which perspective is this analysis, is this from the writing POV?

Lago from Othello is a strongly written character, you see him overpowering Othello in the writing itself

But Rahman doesn't have a layered character, there's no POV of this character, the movie shows him from Hamza's perspective so we don't really know what is going on in his head, we know Hamza can manipulate him, his every action had Hamza's influence

These two characters can't be compared

If it is about how they were portrayed, again, Langda Tyagi's role was central to the story and Rahman was just a pawn in Hamza's game

Rahman wasn't even a villain for the most part, Hamza wrote his name down after 26/11 scene

If we are comparing them on the basis of who can hold attention of audience that enjoys watching reels then Rahman is like Rolex from Vikram

Saif's Langda Tyachi was, is and will always be in a different league. Rehman Dakait pales in comparison.
