The only three movies that worked big time for me were Provoked, Umrao Jaan and Jodha Akbhar. Those were superb movies, with superb acting. And yeah, I also happen to remember a lot of Kuch Naa Kaho, in which she stole the limelight, especially in the end sequence. But apart from that, I don't think she's that great an actress.
That said though, this is Bollywood. Right now, I can't think of one actor or director capable of saying he's sure to hit the bull's eye with a movie - okay, perhaps except Aamir. He's always sure... and he's right too!
Edit: And I definitely agree with Rhea. Hits and Flops don't affect her anyway. She's never judged in terms of her acting capabilities!
