One of the most striking aspects of "Zodiac" is its thought-provoking commentary on the media's role in shaping public perception. The film highlights how the Zodiac Killer's cryptic letters and codes were used as a form of twisted game, with the killer using the media to taunt and manipulate the public. This theme is eerily relevant in today's digital age, where social media and online communication have created new avenues for manipulation and exploitation.
