The trailer for Chasing Butterflies. The “butterfly effect” posits that one small change can affect history by changing the never-ending chain of circumstances that result from that decision. Weren’t Adam and Eve stupid people? She took the Apple, didn’t she? We could still be in Happy Valley if it weren’t for those two idiots, though I’d cut Adam some slack—she was naked and she offered. He was straight and under 50. No excuse, but I see his dilemma. Nevertheless these are our collective parents we’re talking about. Take that to therapy.
