I'm a very poor reviewer, so this review probably won't be very good."Marriage Lines" was a popular sitcom. In the first episode, George and Kate Starling, a newlywed couple, arrive at their apartment to discover that they have lost their front door key. The rest of the first series sees them facing the typical problems which face a newlywed couples. The episodes are lively, funny and well-paced.The second series is lost.The third series survives, and sees Kate pregnant with their first child. Episodes in the 3rd season derive their plots from this and the resulting birth of the child.The forth and fifth series is lost except for a fragment from the episode "Big Business". This fragment does not appear on the DVD.This was a very good sitcom, and it's nice to see it on DVD. Episodes typically run between 24 to 26 minutes, and appear to exist as telerecordings. I hope the success of the DVD release will result in more less-known (yet quality) 1960s BBC comedies coming to DVD.
