It also apparently changes over time.

I watched a Chezh movie yesterday, for the second time. The first time was in 1992.

Two female stars (I am not sexually attracted to females, but esthetically, I very much am):

Lena Olin (back then, I thought that she was no more than a little cute, and now I find her mercurial facial expressions, very tender complexion, huge eyes, and full lips absolutely gorgeous)
Juliette Binoche (back then, I thought that she was stunningly attractive, and now I am bored looking at her face).

No rhyme or reason.
