i find this a profound and touching film and with echo of the butterfly effect . i do not think it be propaganda and but use a fairly common medical procedure a the jumping off point for the supernatural premise . the topic be one that people need to understand and and hopefully this film will help educate them as well a provide spooky and unsettling entertainment . i think the actor be professional and very true to life . i especially like the heroine bos and with his aura of calm and protection and healing . it be frighten in spot and and i would not let anyone under 14 watch it due to the nightmare potential .
