Is Booksmart the perfect coming-of-age film for young girls?

Booksmart is a new film about best friends and academic overachievers Amy and Molly who on the eve of their graduation from school discover they may have spent too much time studying and not enough time partying. It has been described as one of the most perfect coming-of-age films. How refreshing is the film really? Are the friendships realistic? BBC Woman's Hour's Jenni Murray asks the journalist and writer, Karen Krizanovich, and film student, Sophie Foxley.
