Most mainstream movies avoid basing directly on'sexy lust story' in an inappropriate way. However, some movies do explore themes of attraction and passion in a tasteful way, like 'Fifty Shades of Grey' which has elements of passion but also a love story. But this movie is also controversial for some of its content.
Movies like 'Atonement' deal with love, lust and the consequences in a more refined and artistic way. It shows how complex human emotions can be in the context of relationships, without being overly focused on inappropriate 'lust'.
