Love can be a drug. It can haul us, cartwheeling and half-conscious to whatever gods we choose to make sacrifice to. But it can also destroy us. Pitch us headlong into the voids below. Those dark places. The ones we don’t like looking for. And in “Nipples & Palm Trees,” the latest film from director Dylan Reynolds, we find ourselves taken on just such a journey. All the highs, all the lows, and every scratched out foothold in between.
