u r absolutely right. Bipasha does not have any sex appeal. She is just showing her body in many pictures like dhhom 2 omkara . She can not move her body in dance also so her that problem is hiding by way of showing close up on her body .
For sex appeal one should have facial expression,body movements . Now a days all models are coming up as actress by just exposing their body. Only low profile crowd is going to response them nobody eles.
