The Purge (2013)
Goddamn was this ever a piss poor movie with such a wasted premise. Basically it's the near future and America has been reborn as it were with a new government faction called "The New Founding Fathers" wants to keep crime and unemployment low by making all crime legal for a 12 hour period. Now this setup offers up a plethora of questions the film could answer like if scientists use this time to do experiments they otherwise could have done, do hackers or black marketers do their work during this time, wouldn't this be a perfect moment for a country to attack the US, etc. Instead we get
The Strangers and
Straw Dogs human centipeded together with an incredibly heavy handed message that is quite literally stated directly to the camera.
I really hate when good ideas get wasted.
