No subject should be off-limits for filmmakers willing to take a plunge. The degree of difficulty, however, tends to increase sharply with the weightiness of the premise. Dark Night takes an extremely provocative topicโ€”a seemingly random mass shootingโ€”and applies a heavy layer of arty artlessness to the material. Despite a number of striking images (Hรฉlรจne Louvartโ€™s camerawork is never less than severely beautiful), it rarely feels like itโ€™s been thought through enough to really jell.

Inspired by the 2012 movie-theater massacre in Aurora, Colorado, writer/director Tim Suttonโ€™s narrative begins with the aftermath of a copycat Floridian tragedy, and then backtracks to explore a number of the audience members. Although there are plenty of potential candidates/red herrings, the identity of the shooter remains mysterious until the finale.

The sheer variety of styles that Sutton adopts is impressive, ranging from extended dialogue-free passages (youโ€™ll never hear โ€œYou Are My Sunshineโ€ quite the same way again), seedy Larry Clark voyeurism, and even a bit of faux-documentary off-camera prompting by the director. While such an approach does hint at the unfocused existence of its characters (a sullen teenโ€™s description of video games as โ€œsome twisted reality where you get to kill people over and over againโ€ canโ€™t help but sting), it ultimately comes off as more of a blizzardy mishmash of techniques than a coherent statement.

Those bits that do register, however, make this ambitious film frustratingly tough to dismiss. I actively disliked Dark Night for most of its running time, but there are momentsโ€”a wannabe actressโ€™s sad quest for the perfect bathroom selfie, a sudden jarring transition into a Google Earth point-of-view, the revealed murdererโ€™s sunny grin as they excitedly jog toward their destinyโ€”that will be residing in my head for quite a while. Power is power, even when terminally unfocused. recommended
