Why so many failures?
She is beautiful, kind of a good actress and extremely hot. With that potential she could definately be acting in movies that have an imdb rating over 5. But this seems to happen rarely. This of course has made her career a series of failed movies and hot photo shoots.
So why do you think that is? My explanation is that she must have the worst taste in movies and that she is unable to distinguish between a good script/director and a bad one.
