The document provides an evaluation of a film trailer created by the author. It analyzes how the trailer uses, develops, or challenges conventions of real media products. The trailer challenges conventions in several ways: 1) It focuses viewers' attention on the simple film title for an extended period, 2) It films locations in a skatepark and urban areas from a first-person perspective to create immersion, 3) It lets actors choose their own clothes to suit characters naturally. The trailer also challenges conventions through its editing, titles, storytelling approach, character introductions, and genres suggested without dialogue or revealing the full story.
