I remember a debate years ago at school where the topic was 'familiarity breeds contempt', and one side flawlessly argued that in the end, familiarity just breeds.

And thank God for that. In the time period that has elapsed since Lindsay Lohan's generation defining turn in what is quite frankly, one of the best films ever (even with the cop-out ending) the most popular female role in the movie world has evolved from bog-standard romantic heroine to something even scarier - manic pixie dream girl.
