A Guidebook to Killing Your Ex (2016)

A Guidebook to Killing Your Ex is essentially what this movie is, considering it's a found footage horror movie presented as police evidence. The main character, who calls himself John Doe, is really making a video series documenting how to kill your ex, as that's what he's doing - and it seems thinks others might want to do, too. He takes you through everything, from the early stalking to his "test subject," played by Oliva Barta, who bares all three Bs before meeting her untimely end. He's committed to his end goal, but he does find it a little harder than he'd at first anticipated.
