Yes, Deepika Padukone is beautiful with a great figure and I guess she's a DECENT actress, but I'm not a huge fan of her because she has absolutely no personality. If you watch the 2009 Filmfare Awards, her and Konkona Sen Sharma host for a little while, and you can just see how BORING she is! She read the words with a stone cold expression an a monotonous voice.
I think she has been cast in her movies more so for her looks than her actual talent. In Om Shanti Om , she didn't really do much at all, and same with Bachna Ae Hasseno. If her and Ranbir weren't already a couple in real life, then I don't think the chemistry between them would have been believable at all. I hope Love Aaj Kal is a turning point in her career in the sense that she gets a chance to prove that she is a good actress.
