I personally find her to be a very unidimensional actress. Take away SRK and Dharma/YRF there is hardly anything in her filmography which is note-worthy, except Dushman. Among her contemporaries Rani and Priety were far more nuanced and versatile in their acting.
Compared to other actresses, she has worked in fewer films. Its mostly after marriage, she stuck to YRF, Dharma, SRK - but before that she worked in many banners and gave strong performances: Dushman, Gupt, even in some unsuccessful films her acting was appreciated KKKM, Pyar Kiya toh Karna Kya, Hum Aapke Dil Mein Rehte Hai, Pyar toh Hona Hi Tha.
She won best villain for Gupt and started the trend of Female Villains and She was even nominated for HADMRH, U Me aur Mein PTHHT - both non YRF/Dharma films.
