The devastating effects of ALS are on full display in "Gleason," an emotional powerhouse of a documentary charting former NFL star Steve Gleason's battle with the debilitating disorder. With seemingly no restrictions from his subjects, director Clay Tweel delivers far more than just a typical inspirational living-with-disease doc: This is a portrait of a family forced to completely readjust their lives, never flinching from the accompanying fears and frustrations. Tweel masterfully assembles roughly four years of footage, much of it shot by Gleason himself, and the result is painfully raw at times but undeniably rewarding. -Variety
