Why was Jigra got flopped ?

As of now we all know that Jigra got flopped not only at Box-Office but also on Ott. But the main question why it got flopped and why they made Vasan Bala a scapegoat to take all blame. What about Alia? Before release we all heard that how Alia has a boxoffice pull and how all media, pr termed her as Lady Bachhan, Meryl Streep of India, Lady Superstar. So as a superstar isn't alia's fault that she didn't give the opening. Why no one is blaming Alia? Please share your view.
