I knew the Thalidomide storyline was coming, because they gave it away in the Radio Times.
The whole thing felt rather clunky and contrived to me. I didn't see why Patsy and Delia couldn't have just carried on living happily as flatmates - that would have been interesting to watch. Instead we have this ridiculous story where Delia falls off her bike and suffers amnesia - how likely is that? Most cases of amnesia are short-lived. There seemed to be an implication too that the accident had given her temporal lobe epilepsy.
We did notice with pleasure that Delia's mum was the character from Stella who says "cocking" a lot.
I also agree about the deaf woman's speeches - they seemed to be shoehorned in unnecessarily, particularly the one about how she felt about meeting her baby and whether her baby could hear or not hear. I liked the fact that they had a deaf character but it just felt terribly leaden. I also disliked the way once again it was the working class mums who were a bit rude to her (at the antenatal group) while the middle-class midwives and nuns were all terribly sympathetic and right-on. In those days the medical profession was terribly paternalistic and it was very hard being disabled (a lot of people insisted that deaf people should lip read rather than sign) so that didn't seem terribly realistic.
Just felt irritated by Trixie and her Alcoholics Anonymous storyline, which was an unnecessary add-on.
Fred's daughter was horrible, and then suddenly became nice. That didn't seem likely either.
All in all, thought it was a pretty dismal effort.
