badly written characters dismal banality

I could not finish the book: too many unjustified vulgarity, banality, especially in the struggle between the heroine and the Archangel Raphael, implausible, and yet I willingly dives into the bed and I bit believe me in books "normal". The characters' personalities (LUI: beautiful, arrogant ...) (SHE: beautiful, rebellious, aggressive with handsome men) and the opposition of the two is lamentable: it is practically in all the novels under 3 without imagination the woman and the male have this character and interaction. It is disheartening banality and boredom!
