Just started watching this series recently after a friend recommended it. I can't believe it took me so long to get round to watching it. I am completely addicted to it. Have also watched series 1 and enjoyed it just as much. Characters are really well done, despite previous comments criticising Jensen Ackles acting I think he makes the show. His acting is spot on for that character. Music also superb, great soundtrack, the Impala they drive is beautiful, Jeffrey Dean Morgan is outstanding as supporting cast, genuinely gives me 'the fear' some episodes when I have light off. I like that the two central characters are brothers. I was getting really bored of male and female teams because they always bring in a romance at some point and it just kills the action. Overall 10/10. Superb series.
