History YMMV / GoodnightSweetheart

* ValuesDissonance:
** The way Yvonne talks about her Korean business partners as "Oriental sods feeding me God knows what" and blaming them for her miscarriage would seem much more dubious nowadays.
** Gary can be quite homophobic at times - he calls his good double from "Mine's a Double" a poof and when he arrives in 2016 in "Many Happy Returns", he is shocked to see a gay couple kissing in public.

** In "It Ain't Necessarily So", Ron cracks a joke that Creator/StevenSpielberg had bought all of Blitz & Pieces' stock for a new war film. Only a few months later Spielberg would start a new war film, ''Film/SavingPrivateRyan''.

* HilariousInHindsight: In "Fools Rush In", Gary, a time traveler, wears [[Series/DoctorWho a brown suit with trainers and a long coat]].

* HarsherInHindsight: Yeah, "Have You Ever Seen a Dream Walking?" (the episode with the Music/RolfHarris cameo) doesn't get repeated much anymore. And when it does, the nightmare gets cut short just before Harris appears on screen.

* TheyWastedAPerfectlyGoodPlot: In the fifth series episode "When Two Worlds Collide", the portal temporarily opens for anyone and anything, allowing Phoebe and Ron to come and go. This only lasts until the next episode, "Mairzy Doats", with Ron's trip back to the past being a disaster. It would have been interesting for this to go on longer, requiring Gary to set up barriers, or possibly have Ron try to live in TheForties like Gary attempted and learning how hard it really was, only to be unable to go back and be stuck on that side of the portal.

* SugarWiki/AwesomeMusic: In the final episode, at a party to celebrate VE-Day, Gary plays Queen's "We Are The Champions".
* HarsherInHindsight: Yeah, the episode with the Rolf Harris cameo doesn't get repeated much anymore. And when it does, the nightmare gets cut short just before Rolf appears on screen.
* HilariousInHindsight: In the second episode, Gary, a time traveler, wears [[Series/DoctorWho a brown suit with trainers and a long coat]].
* HoYay: In the episode where Gary ends up accidentally splitting himself/cloning himself. [[spoiler: The final Gary, "Good Gary", is gay, and starts to hit on Ron. If these are parts of Gary, you have to wonder what this implies about him.]]
* TearJerker: The old and senile Reg Dedman and to a lesser extent the expression on Gary's face when he meets his grown up alcoholic son Michael in the 1990's and realizes that he had failed as a father by never being there for him.
** Not one single constable or member of staff at his police station found the heart to turn up to Reg's retirement party even though he had been there for twenty five years. He was never well liked and he was incompetent, but to not even give him the traditional pocket watch that Reg mentioned was disgusting. You can see it on his face that he wasn't deluded enough to really believe that they had confused the dates. Leads to a SugarWiki/{{Heartwarming Moment|s}} when Gary tries his hardest to cheer him up.
* TheyWastedAPerfectlyGoodPlot: In the fifth series, the portal temporarily opens for anyone and anything, allowing Phoebe and Ron to come and go. This only lasts two episodes, with Ron's trip back to the past being a disaster. It would have been interesting for this to go on longer, requiring Gary to set up barriers, or possibly have Ron try to live in the 40s like Gary attempted and learning how hard it really was, only to be unable to go back and be stuck on that side of the portal.
** In the finale, Yvonne finally learns about the time travelling but her confrontation doesn't really go anywhere and it isn't until the portal's closed that she learns what's going on.
* UnintentionallyUnsympathetic: While there are times when Yvonne is right to chew Gary out, at the end of the season 4 episode ''In The Mood'', she gives him a long-winded, self-righteous lecture for losing their nephew Arthur before storming off to have a girls night out with her friends. In addition to Emma Amos' mediocre acting making the rant more annoying than funny or impactful, it also comes across as very hypocritical for Yvonne to lecture Gary about taking responsibility for a child, when she earlier claimed to be too sick to look after Arthur herself, but is now well enough to go clubbing with her friends.

* TookALevelInJerkass: When the new actress for Yvonne took over in Series 4, Yvonne became considerably more bitter and demeaning towards Gary in comparison to Series 1-3 Yvonne.
