Supernatural is a Tv series which is mythical tv serious full of mythical creature, on air from 2005. now its running 11th season . I will personally recommend you too watch up to 6th season . after that nothing in this tv serious . up too 6th season a 1 very big story was running after that , new story were came but not so powerful like first . the first 6 season of this tv serious was awesome . story was very cool . the first story about two brothers those the become a play thing form angel and demon play thing .they use them for there own purpose and try use them in there fight . but two brothers are get out from there manipulation and save the world there own way . the special effect quality was not good enough .but OK for tv series.i will definitely recommend this up to 6th season after that your choice you want too see that or not, may be you also like from 7th season.
