Emma Stone simply owns this film from the first reel. Taking liberties with "The Scarlet Letter" roots, the film tells the story of Olive Penderghast dealing with high school level rumor and innuendo of sexual promiscuity, and deciding to fully own such notoriety, even at the expense of friendship and reputation and self-esteem, but events go twisty and Olive finds herself in some larger scale drama stemming from lies and the cover-up of lies, but with the help of her quirky parents, Olive regains her footing, but at what costs? The script is very funny, the adult characters have a lot of fun playing with the script, and it works. It's not bust-out raunchy funny for the most part, but the movie makes you care about Olive and her situation, the pacing is pretty solid, and the casting is pretty much on-point. I give it 3 stars, or a grade of B.
