"Arrival" Alien's with Amy Adams as an Intergalactic Linguistics Expert

"Arrival" is a contemporary sci-fi movie direted by Denis Villeneuve ("Incendies" 2011) starring Amy Adams (Dr Louise Banks) and Jeremy Renner (Dr Ian Donnelly.)  It takes a realistic approach to how our world would respond to alien space crafts landing simultaneously in various parts of our world.  In many ways this echoes "Contact" with a realistic examination of the expected co-operation & disconnect between power house nations.  At first, all 12 countries align global communications to share information.  It's not long before China & Russia pull out of the pack threatening aggressive attacks on the gigantic, alien (a not so politically corect term) spacecrafts.  Louise is brought in as a linguistic expert assigned the improbably task of deciphering messages transmitted by the intergalactic space travellers.  The anti-gravity affects, military protocols, mystifying aliens & hieroglyphics are all credible & intriguing.  The celestial sic-fi plot takes a cerebral leap of faith that outshines other E.T. storylines.  "Memory is a strange thing.  We're bound by it with a beginning and an ending."  While working to save humanity, Louise sees dreamlike flashbacks of her daughter Hannah from the joys of infancy & early childhood to her heart wrenching death as teenager.  Hannah's special name is a palindrome; spelled the same forward or backwards.  I interpreted this captivating & beautiful alien invasion movie more as an intelligent paradigm of time travel.   Would you live your life over knowing the future?  I'd go back and see "Arrival" again.
