Proofread this excerpt from a review of the film The Perks of Being a Wallflower. Which sentence contains punctuation errors?

The Perks of Being a Wallflower is a charming little coming-of-age film based on the novel of the same name. The film vividly depicts some of the struggles teenagers go through on their quest for growth and self-identity. This struggle plays out chiefly through the protagonist; Charlie, who anchors the film brilliantly. Charlie isn't your typical "leading man" by any stretch of the imagination. However, there's a softness and vulnerability to his character that makes him strangely endearing.
