I think i am addicted! Note sure why it has taken me so long to get into this but im so glad I did. Brilliant acting. Genuine characters, realistic action and response to fires/accidents etc. And the characters' storylines are wonderful. Cant get enough.... literally binge watching from the beginning so nothing else is getting done in my house. heehee. at the end of season 4 - so much more still to go. Thanks to all who made this possible!
