Summer winds down, with under-the-radar new releases including faith-based drama, independent comedy and documentary about a death-defying mountaineering expedition.

We Are Your Friends (pictured) drifts through multiple sub-plots and settings, yet effectively (and energetically) captures a generation unsure of how they can find success. The faith-based drama War Room wallows an an infantile concept of prayer that turns God into a genie. Noah Baumbach's new comedy Mistress America is a charming character study until it shifts into shrill farce. The exhilarating documentary Meru chronicles the attempt to scale a never-before-summitted peak through remarkable GoPro camera footage.

MaryAnn Johanson acknowledges the visceral effectiveness of the escape-from-revolution thriller No Escape, even through its implausibility and cultural narcissism.

Andrew Wright sees the remarkable collection of personal footage and notebooks in Kurt Cobain: Montage of Heck as both exhaustingly shapeless and perhaps the best way to capture its enigmatic subject.

In this week's feature review, The Diary of a Teenage Girl explores adolescent teenage sexuality with a welcome frankness and complexity.
