History Series / OneDayAtATime2017

* StudioAudience: Unlike most sitcoms of its era, ''One Day at a Time'' is taped in front of a live audience. This is particularly apparent with Lydia, played by screen legend Rita Moreno[[note]]One of [[UsefulNotes/TheEGOTs fifteen people]] to win an Emmy ''and'' an Oscar ''and'' a Tony ''and'' a Grammy.[[/note]], as her first appearance in most episodes tends to be greeted with loud cheering.

* ButNotTooBlack: A Latinx version. Elena is horrified to realize she's inadvertently been passing for white due to her lighter skin color.

* SlapSlapKiss: In "One Valentine's Day at a Time", [[MyBelovedSmother Penelope]] and [[OverprotectiveDad Mateo]] end up arguing about who is more overprotective before making out in Lydia's room.

* RemakeCameo: Mackenzie Phillips, who played one of the daughters in the original series, plays the coordinator of the women veterans’ support group.

* AdultFear:
** Carmen's parents getting deported, resulting in Carmen's life being turned upside-down, and her being homeless for a brief period.
** When Elena finds out [[spoiler:Lydia's not an American citizen]], she's ''terrified'' that something similar could happen to her.
** The episode "Hello, Penelope" is full of it.
*** First, the idea that you may have to be on antidepressants for the rest of your life, simply to function normally. There's no shame in being on medication, but the stigma around it and mental illness is still very much alive, and it shakes Penelope to the core to realize this.
*** Then, when Penelope goes off her meds, she suffers rapid downward spiral throughout the episode, and is simply unable to keep her life on-track, or her emotions level. Objectively, everything is fine, and she ''knows'' it, but she simply ''cannot be happy''.
*** This can be also explained with Penelope stopping her meds suddenly - anti-depressants need to be gradually decreased otherwise there are significant withdrawal effects.
*** When Penelope snaps at Schneider when he is only trying to help her falls under this. Having someone you care about, especially your best friend or family member, snap at you and belittle the issues that you have is a horrible thing to experience, especially if you were just trying to talk to hep them out when they were obviously struggling. Made worse that the issue she choose was his drug addiction and horrible childhood.
*** For Lydia, watching her child suffer so much, knowing there's nothing she can do. [[spoiler:And then realizing that she probably inadvertently made it ''worse'' with her anti-medication stance.]]
*** Finally, Penelope having to tell her boyfriend, unsure if he'll still stay with her once he knows. [[spoiler:He does.]]
*** The idea of your close friend or family member [[spoiler:being suicidal.]]
---->'''Penelope:''' I know what the last part sounds like, but I promise I would never do anything like that.\\
'''Schneider:''' I know. But I think you know that healthy brains do ''not'' go to that place.
** The whole family and Schneider, especially Penelope, have to deal with the very real possibility of [[spoiler: Lydia dying when she has a stroke.]]
** In "Locked Down" when Penelope finds out Lydia has a gun.
--->'''Penelope:''' No matter where you hide it, kids find it. And accidents happen. And things that aren't accidents. We have teenagers in this house. We have a ''gay'' teenager in this house. We have a veteran with PTS. This is the last house that should have a gun.
** "Outside" has Elena and Syd sharing a story about a couple of boys following them around, telling them to kiss until they lost them in a crowd. Penelope follows it with the story of a former mentor for her in the army who one night came into the office drunk when she was alone and touched her inappropriately.

* MoralDissonance: The show is mostly great at giving solid morals and narratives, but in "No Mass" there's some questionable statements. Though eventually Penelope apologies to Lydia and they compromise, both Penelope and Elena said some things that are very negative to religious people. At one point the all-embracing "I'll make you comfortable even if I'm not" Penelope mocks Lydia's faith in God as being her personal imaginary SecurityBlanket, which was uncalled for even if that's what she thinks -- Lydia was just saying that she'd like to go to Church and not have Penelope tell her not to.

At one point the all-embracing "I'll make you comfortable even if I'm not" Penelope mocks Lydia's faith in God as being her personal imaginary SecurityBlanket, which is very [[SeriousBusiness Not Cool]] and was uncalled for even if that's what she thinks -- Lydia was just saying that she'd like to go to Church and not have Penelope tell her not to. At another point in the episode, Elena goes against her own moral code in a different way; specifically, the atheist Elena tells Lydia to refer to God by gender-neutral pronouns. Even if Elena did believe in God and believed that God had no gender, she is the show's main advocate for using the pronouns not that you personally like, but that the other party does, and it should be clear to her that Lydia always has liked using male pronouns for God. Telling her to do otherwise is equatable with telling a person's friends to refer to them using a different pronoun to what either of them want. Lydia plays this off by making a quick snarky one-liner, but would be well within her rights [[WhatTheHellHero to be upset with Elena]] for trying to tell her to do that, and furthermore because in Spanish the distinct pronoun for God is Él and so functionally and culturally ''needs'' to be male unless you want to be really offensive.

* PlatonicLifePartners: Penelope and Schneider are great friends, but they're clearly ''only'' friends.

* RememberTheNewGuy: Penelope's brother Tito, who went unmentioned through the first two seasons despite the heavy focus on the family dynamics. He shows up in season 3 and is called up for his distance from the family.

** The curtain isn't thick enough to block out sound; People frequently behind the curtain hear things they weren't supposed to.

* SlapSlapKiss: In "One Valentine's Day at a Time", ][[MyBelovedSmother Penelope]] and [[OverprotectiveDad Mateo]] end up arguing about who is more overprotective before making out in Lydia's room.

* RomanticTwoGirlFriendship: Elena and Carmen are very close and physically affectionate, with Penelope and Lydia suspecting that they may not be just friends. However, [[spoiler:after Elena comes out]], she confirms that Carmen is straight and that their relationship is purely platonic.

* AdaptationalDiversity: The original series was about an Italian-American family. Here the family is Cuban-American, and one of the daughters is a lesbian (with a non-binary partner).
