Juno is strong, prideful, and passionate. It is difficult to maintain a role as both protagonist, and antagonist; Juno does that. She is both villain, and action hero. Watching this movie, I fell in love with her--she's not evil, she's just fundamentally flawed, as is everyone. Although she is physically strong, she is emotionally weak. Juno is not a BAD person--she is simply an adrenaline junkie, and is trying to make up for her affair with her best friend's husband.
