I dunno about that anymore breh, Zodiac happened eight years ago.
Anyway,
not a movie but a tv-show but I'd remake
Hill Street Blues as a movie set in present day, following multiple people working in (or coming to) an undermanned police precinct at the height of racial tension following the shooting of a black kid. So the commissioner and the mayor are trying to deal with all that but at the same time they still have ongoing investigations, arrestees that need to be taken into questioning with lawyers, probation officers, social workers and internal affairs all over the floor, etc. etc.
And I'd remake
Daybreakers, the "what if vampires become the dominant species" movie by the brothers who also did Predestination, but this time we'd actually do something good and interesting with the concept.
