The document discusses how the opening sequence of the media product "Just a Crush" uses conventions of the thriller genre. It establishes a stalker as the antagonist through imagery of stalking photos, notes, and weapons. Mise-en-scene elements like lighting, costumes, and positioning convey the stalker's obsession. The music and titles are inspired by the film "Se7en" to create tension. While most stalker films feature a male stalking a female, this film challenges the convention by having a female stalking a male victim.
