While Liv Tyler is the "star" of this film she is only one facet of a beautiful film. While many comments focus on the coming of age plot line. This film not only presents a sexual beginning, but also an emotional journey. With the death of her poet laureate mother, Lucy (Liv Tyler) must find her way to emotional and sexual adulthood. Fortunately, the film never gets bogged down, or depressing.
Set in the lovely Tuscany province, Lucy's father sends her to spend time with friends of her mother and pose for an artist. Several of the characters are transparent, and easily understood, others are far more complex. Like life not all the answers are give, but the film rewards the viewer on multiple levels.
Enjoy watching the secondary characters grow in their own ways as well.
I hope this helps you.
