These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: To name a few: Estela Reynolds, Violeta Recio, Judith Bécker and Fermín Trujillo. Between the secondary characters, la Chusa and Parrales are very popular.
Fanon Discontinuity: Some fans pretend that the first season or the first two don't exist or are from a different series from the actual series post-Season 3. Others who think that the show declined in quality from Season 5 onwards, often pretend that the show ended in Season 4, since luckily, its season finale could easily be considered the series finale if the show had been cancelled.
Ho Yay: Between Enrique and Antonio, so much. It's particularly taken Up to Eleven in Seasons 2, 3, 4 and 7.
From Antonio confessing his love for Enrique and kissing him, to them sleeping in the same bed together with their arms around each other, to hugging each other lots of times and always touching and holding each other with No Sense of Personal Space, to Enrique being a Love Martyr to Antonio and always protecting him from other characters and dangers, to them bickering Like an Old Married Couple, to them having sex once and Antonio masturbating in front of Enrique once as well, to Antonio caring far more about Enrique than about his own wife as he's obsessed and co-dependent on him, to Antonio always trying to sabotage Enrique and Judith's relationship due to himbeing jealous of her, to Enrique leaving his entire life behind including his girlfriend and presidency of the Community which is what he has always wanted for Antonio, to them faking they're a couple on many occasions and other characters mistaking them for a couple, to Antonio often coming over at Enrique's like if it were his own house and living with him on several occasions, etc.
Jerkass Dissonance: Antonio, who is widely considered, along with Amador and Estela, the most popular character in the series.
Jerkass Woobie: Antonio. He's an insufferable lunatic man with sociopathic tendencies who no one in their right minds would want to be friends with, but at the same time, hislifehasbeensotragic that it's not difficult to understand why he is now like this and sympathize with him. Also, his catchphrases are funny.
However, he's starting to lose that sympathy due to him crossing the Moral Event Horizonseveral times. To the point that he's so pathetic and miserable that he fails to make an angry response.
Launcher of a Thousand Ships: Estela, who has tried to sleep with almost every neighbour. Some examples include Estela/Leo, Estela/Enrique, Estela/Coque, Estela/Amador, Estela/Javi, Estela/Fermín, Estela/Maxi etc.
Enrique has been paired up with a fair amount of people as well, such as Enrique/Nines, Enrique/Raquel, Enrique/Judith, Enrique/Estela, Enrique/Coque, Enrique/Antonio, Enrique/Maite, Enrique/Araceli...
Other characters fit the trope as well, but oddly enough, Amador and Antonio, who are the two characters most obsessed with sex, are the ones who have less ships involving them. Justified in both cases, since Amador mostly hooks up with guest stars and never stopped loving his wife to begin with, and Antonio is usually too obsessed with the presidency of the Community to care for anything else.
Romantic Plot Tumor: The Enrique/Judith romance is as loved as it is hated, for not only being in a Break Up Make Up Scenario-dynamic for four seasons straight, but also for being so all-consuming that other larger storylines are moved to the sidelines in favour of more Wangst between the couple. It doesn't help either that Judith has been so painfully mean to Enrique that one has to wonder what he sees in her anymore.
The "Cuquis" might be considered a milder version of this.
The Scrappy: Fran, Enrique's son, was very disliked by the fans after season 3. Also, Reyes from season 5 was so disliked that she didn't make it into Season 6 despite her actress wanting to.
Tear Jerker: Despite being a comedy series, the writers tend to make the characters very miserable, with the most dramatic seasons being Seasons 4, 6 and 7.
In the Season 4 premiere, Antonio is seen crying and asking his missing wife through his voice mail to come home as he feels very lonely and depressed without her and without Enrique who he thinks is dead. Later in the same episode, Enrique gives a teary-eyed Antonio a heartbreaking "The Reason You Suck" Speech which eventually results in Antonio threatening to kill himself while sobbing. This happening at the same time that la Cuqui's father dies and she and her mother are seen helplessly crying over him. The fact that Amador is the one who unintentionally caused it only makes it worse.
In the Season 4 finale, Goya dies and Vicente tries to protect Javi by lying to him. He eventually finds out and it turns out to be a very sad moment. In the same episode, Antonio finds out that his friend Coque is Berta's lover and tries to kill him but can't so he throws his gun away, which had been so important for him all this time, and leaves defeated as his wife calls him worryingly. By the end of the episode Antonio finds himself utterly alone after his only friend Enrique betrays him and loses the presidency of the Community. Antonio in tears saying that he has nothing left as he wanders alone on the street is a really heartbreaking scene. The entirety of the episode is actually a big Tear Jerker for most characters.
In the season 5 finale, Amador fakes his death but doesn't tell Maite. When she discovers that he is "dead"... Well, her reaction tells everything.
In the tenth episode from season 6, the "Cuquis" find out that they will be evicted by the bank and start crying and hugging each other, showing that after all they care for each other. The whole story arc about them being evicted and homeless during Seasons 6 and 7 is quite a big Tear Jerker, especially when not even their friends are willing to help them and the "Cuquis" are left to live in the garage.
In the Season 6 finale, there's a significant Tear Jerker moment when Antonio finds his birth mother and falls down on his knees and hugs her while crying, but she abruptly pushes him away.
Episode 7x12 could easily be considered the biggest Tear Jerker episode for Antonio, and that's saying a lot considering his history.
Why Would Anyone Take Her Back: Enrique and Judith: he really shouldn't forgive her after everything she has done to him and yet he always does. Enrique and Antonio are a non-romantic version of this. In both cases it's mainly because of Enrique being a textbook Love Martyr.
