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.
Alas, Poor Scrappy: Although fans were cheering when the tram crashed down on Molly Dobbs, the scenes afterwards with her and Baby Jack in the rubble were very sad. The baby survived anyway.
Non-fatal examples. Teresa and Natasha weren't well-liked but their exits were well received. Teresa realised that Lloyd was growing closer to Cheryl and opted to leave herself, realising their relationship would come to nothing. Her final scene has her waiting for Lloyd to leave before tearfully calling her son Daryl - implying she's going to patch things up with her family. Natasha meanwhile decided to walk around giving numerous people a "Reason You Suck" Speech - saving Gail Platt for last. She busts Gail for hacking into her medical records, getting her fired from her job. Her line "Back of the net!" was a couple years too early for Memetic Mutation status though.
Angst? What Angst?: You can't help but notice how eerily well Peter Barlow took to two wives suffering two miscarriages between them. While each woman dealt with the devastation in their own way, he on the other hand took in stride and sadly cemented his Jerk Ass persona.
Arc Fatigue: The Domestic Abuse storyline. A full year after it started, it appeared to have reached it's conclusion - only for the Kirsty to find out Tyrone was planning to leave her immediately after they got married so he could get parental rights to his daughter. Kirsty then fell down the stairs after Tyrone moved out of the way of her attempted strike and accused him of abusing her.
Tracy Barlow's obsession with Steve Macdonald. Even Kate Ford, who plays Tracy, is sick of it at this point.
Celebrity Paradox: Nobody ever watches TV; Nobody in the street seems to have noticed a sudden infestation of meerkats, a species native to South Africa, and are asking whether this merits intervention by the zoo, the RSPCA, or Rentokil (An insurance company using anthropomorphic meerkats as mascots is "sponsoring" the show, with commercials at the start and finish of each segment.These feature the lovable animals drinking in the Rovers, dining in Roy's café, and doing other cute meerkat things.
Michelle discovering that Ryan wasn't biologically hers, swapped with another boy called Alex. Alex disappeared after a few weeks and the storyline was panned by fans and critics. The writers appear to have retconned it from existence now.
Kelly and Molly's affair was universally despised, for Strangled by the Red String and downright uncomfortable love scenes. Karl and Sunita's years later was almost like a Recycled Script of it - and was equally hated.
The 'relationship' between Jamie and Frankie. Numerous viewers and critics expressed Squick at it. Even Frankie called it off when it got too icky for her.
Ken abruptly leaving Deirdre to go and live with Denise, hoping to rekindle his relationship with his son Daniel. Mostly because viewers found it a waste of time and knew Ken and Deirdre would inevitably reconcile. Fans also felt a similar way towards the affair with Martha - as it seemed like an odd way to shoehorn Stephanie Beacham onto the show.
Sophie Webster was one as a teenager. Fans loved her Deadpan Snarker tendencies as she often played the comic relief to Rosie's drama queen tendencies.
Maya Sharma quickly entered Magnificent Bitch status when she managed to get Sunita arrested on her wedding day - by marrying several other men in her name and busting her for bigamy. Let's not get started on her revenge after getting released from prison.
Germans Love David Hasselhoff: The show is very popular in Canada and in recent years, has their airing only trail the UK's by a week (versus a decade ago, when it was nine months behind.)
Kevin Webster (during the War of the Websters storyline). His wife Sally was a borderline example too, though she at least got several Take That, Scrappy! moments.
Nick Tilsey. Although he has always been seen as Gail's "perfect" child, he has horrendously backslid into this since being portrayed by Ben Price.
Memetic Mutation: Granted, it was before the internet became as prominent, but the "Free The Weatherfield One" campaigns that sprung up across the UK after Deirdre Rachid (presently Barlow) was falsely imprisoned.
Ascended Meme: You know a storylines successful, when the Prime Minister of the time comments about it in Parliament.
Replacement Scrappy: Sylvia Goodwin and Gloria Price were two lackluster replacements for the popular and well-loved Blanche Hunt. Fan reception to both women were lukewarm at best and both characters were gone within less than two years of their respective introductions.
Tina. She gradually became this in the eyes of the fans of the show, after her cheating with Peter after knowing full well how horrible it is — see above— and her Jerk Ass behaviour (threatening to report Rob and Tracy's illegal merchandise simply out of spite) before she died. Another cause was her being featured too often in every scene leading up to her death.
Janice Battersby. There have been many more over the years, but most are either Rescued from the Scrappy Heap or written out, whereas Janice has remained for years despite the fan's dislike.
Kevin got very unlikeable too in recent storylines, although some think Kevin was arguably worse back in 1997 and 1998 with his affair with Natalie Horrocks and Sally's affair with Greg Kelly. Even throughout the 2000s prior to his affair with Molly, he was only the lesser of the two evils regarding him and Sally.
Sean Tully. Very hated by fans, some suggesting he is still there because he is friends with the producer.
Peter has been placed back here post-2011. Given his gratuitous affair with Carla, which led to a disaster of a marriage, which was already marred by their respective drinking problems, meddling from his ex-wife and Simon detesting her as a stepmother. Then he had the affair with Tina and things only got worse.
Kirsty Soames. In addition to her long, long storyline, she was just unpleasant and manipulative and made you feel really bad for Tyrone to go from one horrid excuse of a lover to another in such a short time.
Stoic Woobie: Eileeen Grimshaw refused to cry in public even at her father's funeral. Occasionally slides into Jerkass when she expresses affection through yelling.
This is of course a regular trope, but a particularly memorable occasion was a 80s scene of fan favourite Hilda Ogden opening a parcel containing her recently deceased husband (and fellow fan favourite) Stan's glasses, and her subsequent breakdown into tears.
The Fiftieth Anniversary. Explosion, train crash, deaths, war flashbacks, fires, injuries.
John Stape's death.
Hayley Cropper's death. Oh dear GOD.
They Wasted a Perfectly Good Character: Poppy was widely liked by fans, awaiting some kind of plot for her. The most she ever did was tell Tara that Dev cheated on her with Lisa. She was abruptly axed when she got into a few arguments with Betty in the pub.
Natasha spent ages as a side character, aside from a brief fling with Tony. The first time she got any kind of focus was the start of her exit storyline.
True Art Is Incomprehensible: Played with in an episode. Toyah Battersby, an art student, tries to pass off her slovenly step-father Les' chair, covered in debris such as empty beer cans and old cigarette stubs, as her art project to her tutor. He tells her about an occasion where he had a student who tried to pass off a pile of bricks as his art project, which the tutor didn't buy, and he failed him. He then asks Toyah to explain how her "project" is anything other than a ratty chair covered in rubbish. She improvises a pretentious explanation about how it represents the British working class, which the tutor doesn't buy, until he sees Les for himself, and agrees it is an accurate representation of him, which causes him to not only give her a high grade, but also recommend her project for an exhibit. Its particularly funny because Toyah literally threw the whole thing together at the last minute using the first things that came to hand, because she had neglected her project until only moments before the tutor turned up at her house.
Unintentionally Unsympathetic: Nick Tilsley, especially during the whole "Who's the Daddy?" storyline and its aftermath. As unfortunate as it is to have lasting brain damage, it was still his own fault for sleeping with his brother's wife on Christmas. He should have known by now who his brother was, what, if pushed far enough, he was capable of and should have just manned up and confess to David and Leanne in the first place. Plus, in addition to being an unsympathetic character already, it may come off as a form of Laser-Guided Karma for sleeping with his then-best friend's wife in a year earlier while said ex-best friend was recovering from serious injuries he had sustained.
After their mother died in 2013, Asha and Aadi Alahan.
Tyrone Dobbs. Full stop.
David Platt. It was hard not to be feel sorry for him when he was kicked out of his own house, denied access to his kids and treated like a complete monster in late 2013. All for 'trying to kill' his brother Nick (which was a genuine accident).
Todd Grimshaw. He was not allowed to see his premature baby son Billy when he was alive (as Sarah and Gail wouldn't let him). He only got to speak to him at the baby's funeral.
