Why Twinkle Khanna couldn't make big in BW?

She is the daughter of first superstar Rajesh Khanna, she was really beautiful in her 20's and she is still beautiful now, she worked with all three Khans and other superstars in the 90's like Govinda, Akshay and Ajay, she also gave hit movies but she still failed to establish her career in BW, I saw her movie Mela with Aamir few days ago, she looked very sexy on that song Tujhe Rab Ne Banaya Hai Kamaal and acted pretty well on that movie too but sad that movie failed and after that she left the industry, now she is only known as a star wife and writes book, some people calls her Miss. Funnybone book and she keep getting troll on Twitter after she makes silly comments but I want to know what happened to her career? I know many people will say that she can't act but so is many actresses that can't act nowadays and even in the 90's, many actresses couldn't act very well but somehow they lasted in the industry longer than Twinkle.

I swear there was a similar thread just recently and i made a post. Maybe i dreamt it. But anyways my two cents...

She cannot act

I loved her in this song in particular:

Simple her acting was as lame as her. "Witty" remarks

I only liked her in Baadshah. I can't tell if it's cuz I was raised on that film or because she was genuinely good in it though.

Yes she couldn't act. She was also a part of one after another god-awful films. 😆

Also despite her being conventionally good-looking, I never found her beautiful or hot... not even a bit. 🤔

Did u just say she acted pretty well in Mela.. m sorry I know dats ur personal opinion but never have I ever heard anybody praise her acting in Mela..she made an already bad movie tortorous wid her acting..God she was so so bad.
She is beautiful no doubt bt she is a very bad actor.

Twinkle herself admitted she is a terrible actor.

Have you seen her character Rupa in Mela?😲 Good she left acting.
