I have just watched all 3 series on DVD and cannot recommend it highly enough. First and foremost the writing is awe inspiring, coupled with each and every actor at the top of his/her form will leave the viewer with much food for thought. I am 52 years of age and naturally have no first hand adult knowledge of the times (1930's - 1960's) or the geography & industry of the setting, but if you have any interest at all in social history this is an absolute must. I genuinely did not want to reach the final episodes, I feel I've lost something without an episode to look forward to...It will not be too long before I watch all 3 series back to back again, so deep does the writer delve into each character over so many episodes one cannot fail to totally immersed into the lives of such brilliant portrayals...Please take time out to watch Sam if you ever have the opportunity, I assure you you will be glad you did.
