Stree worked because of which factor?

Stree was a small film, but its success was high. No-one expected it to become a 100 crore grosser. What factor made the film such a huge hit?

Vote and Comment.

The genre + great comedy + fantastic casting of supporting leads

Shraddha was not a factor and she didn't benefit as much from it even though the film was a huge hit.

It was a really well made film ..Attributing it to Shraddha is bit too far fetched because Batti Gul tanked three weeks later .RR has zero STAR POWER .

I think the screenplay+acting of the supporting cast mainly.

Mystery. They pointed out quite early on the story that Shraddha could be the dayan and people would want to know if she really was.
