The keyword phrase functions grammatically as a compound noun phrase. The core components, "Patriots Day" and "Stronger," are proper nouns that name specific films. The entire phrase serves as the subject of inquiry, making the noun the essential part of speech for establishing the article's main point.
The preposition "vs" (versus) establishes a comparative or contrastive relationship between the two proper nouns. This structure signals that the article's purpose is a direct analysis of the two entities themselves. The keyword does not describe an action (verb) or a quality (adjective); it identifies the specific subjects for a comparative study, focusing on their respective attributes, themes, and narrative approaches to the same historical event.
For the article, treating the keyword's components as nouns is crucial. This dictates that the central thesis must revolve around the characteristics of the two films. The analysis should explore and contrast tangible elements such as narrative structure, character development, and thematic focus. The grammatical function requires the content to be an exposition about these two subjects, making a comparative analysis of the nouns the primary objective.
