Again the Ringer 

Tall Girl is a 2019 film that centers around Jodi (Ava Michelle), a 16-year-old girl who's 6 feet 1 1/2 inches tall. Since her childhood, she's been insecure about her height and worries that she won't be normal like the others at her school since everyone else is of average height. But when a foreign exchange student from Sweden comes to her school, her life is turned upside-down as she is caught in a love triangle.

This film will discuss the concept of love triangles to viewers.

Typically, a love triangle consists of three people: two people of the same gender and one person of the opposite gender. Two people of the same gender compete for winning the affection of the person of the opposite gender. For example, two girls will compete for the attention of one boy in a love triangle.

Tall Girl explores multiple love triangles. Since this film mostly takes place in a high school environment, the movie has many elements centering around high school life. Some of these elements include the protagonist, who is often the odd girl outside of the high school groups, the antagonist, who is the popular girl and high school bully, a foreign exchange student, who becomes popular among the ladies, two other outcast students who are friends with the protagonist, and the girl who plays as the antagonist's sidekick.
