JellyKitten, the primary thing that all my relatives comment on (I remember when a group of us watched it which may have been the Christmas special) is how it doesn't look like Poplar. Half of the, wouldn't believe it to be set in Poplar, because even when I grew up in the seventies there were constant reminders of the blitz. In the fifties there would have been loads of bombed out ruins all over the place. I don't know if you know the area but poplar is right on the Thames, the Germans used the river as a guid so Poplar was one of the worst hit areas. Plus the place was bloody filty. Most people not 'the unlucky few' as shown by the programme lived in horrible little set ups. Typically you would hear the rats under the floorboards constantly and lots of horrendous infestations. Also as I said, its on the docks so there was a massive amount of muck that came from that.
Secondly at that time, nearly all women in the area were sent to the East End Maternity Hospital up Stepney. My mum was born there in 1950, and my brother was one of the last babies to be born there. Across my entire family, which is very large, all babies for that time period were born there and thinking of all the friends and neighbours in the area, it was only quick/very sudden labours or the rare case who weren't. My great aunt was living in Dagenham for the entire 1950s and even she was sent to the East End Maternity along with all her neighbours. As its a memoir I think they may have over simplified the area because the only way we could see that the midwives would have so many patients would be for them to go further afield than poplar.
I think the aspect that most annoyed my family is how cheery it is. As if it was some sort of golden age. That area at that time, it was grim, not as grim as pre-war but pretty bad. It was rough and poor and dirty and most people were looking to escape. I think I'd have to talk to my mum and gran to find out what they objected to most as its a while since we watched it but I imagine its very much the alright guv'na, Rosie Lee, Chipper cockney attitude combined with the rose tinted view of the place.
