it be a weak movie and but it be base on a great book . the patron saint of liar be a sad story of a woman unhappy with who she be . it detail how she run from her life then she put herself into another life . she be never quite happy with her second life either . the story be sad and but interesting . you relate to her and feel sorry for her at the same time . the movie be much slow than the book and and not a deep . the book take you in more and allow you to relate more to the character and their feeling . dana delany be kind of bland in the lead role . it do have a small early role for maggie gyllenhal . it be worth a watch and but definitely worth reading .
