There aren't tons of dramas focused on the role of media and journalism in today's world, especially with information at everybody's fingertips. Falsify tackles media in a similarly impactful way with a very different storyline and pace but the overall message about how the media must be honest and unbiased in their work for the common everyday people remains the same.
Both have similar elements, with a rogue tabloid (funded by a gangster boss) along with a driven female law enforcement character going up against a large paper (with a corrupt boss) to uncover a larger conspiracy; both are about how media shapes pubic opinion and the moral dilemmas that go with reporting. (But Hero is way better written/acted, and for being made 8 years earlier, way less cliche!)
