Day 91 is a cautionary tale about drugs that never quite comes together. It’s confidently filmed and acted, but it’s hard to justify the way the story has been told. This is an instance of style and content clashing big time.

The movie is broken up into succinct chapters, each dealing with a different character: John, Tina, Laurie, Amber, Jason and Nick. Doug Liman’s spectacular Go had a similar structure, but in that movie the chapters were used to develop characters and delineate complicated jumps in time. Nothing like that is going on in Day 91. We hardly even get to know these people, and because of that, the tragedy at the end of the film lacks real impact.

The title refers to how many days the main character, John, has been clean. His sister, Laurie, gets involved with the wrong crowd and starts using drugs. John tries to save her, but it turns out to be too little, too late.

At the climax, John turns into a mindless avenging angel – a cinematic cousin of Kevin Bacon in Death Sentence and Gerard Butler in Law Abiding Citizen. While impressively staged, the action feels completely empty. All of the time the filmmakers spent introducing us to new characters could have been spent developing the relationship between John and his sister.
