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.

YMMV: Sons of Anarchy
Alas, Poor Villain: Clay's death is oddly moving and saddening even though most fans agree that he was on the show about two seasons longer than he needed to be.
Margaret Murphy (Tara's Boss) being a biker chick in her younger years. That kinda came out of nowhere.
Romeo and Luis being CIA and completely negating the Potter investigation in season 4. Also the Irish suddenly refusing to work with anybody but Clay.
An innocent bystander being randomly killed who coincidentally has such a ruthless and powerful immediate relative that the situation becomes a real threat to the survival of the Sons as a whole. Pulled off not just once, but twice (with Pope's daughter and Toric's sister).
Award Snub: Katey Sagal did win a Golden Globe in 2011, though.
Badass Decay: Toric is introduced as a vengeful Genius Bruiser with military training, police contacts and an Ivy League degree. In the next season, it's revealed that he's a paunchy, strung-out junkie who makes a few major mistakes that utlimately cost him his life.
Jimmy O'Phelan is a member of the True IRA, an Irish terrorist organization and criminal syndicate involved in gun running with the gangs in California, chiefly the motorcycle gang SAMCRO. Unlike the other gang members in the show he has no real loved ones or shows remorse for any of his crimes, and there seems to be no point behind his actions beyond power, cruelty, and trying to save his own hide. O'Phelan ran current SAMCRO member Chibs out of the IRA years before, then married his wife Fiona and adopted his daughter Kerrianne. When he tries to mend the business relation with SAMCRO he meets with Chibs again, gloats that he took what was his, and threatens to dump Fiona and marry Kerrianne next because he says her mother has become too old. Enraged, Chibs gives him up to the authorities, and O'Phelan flees back to Ireland. He withholds information about Jax's kidnapped baby son Abel to maintain the good dealings with SAMCRO. He goes rogue when the IRA intends to demote him for his failure in the States, and he plans to destroy SoA's Belfast chapter to take over the IRA himself. He tries to have SAMCRO killed in an explosion in which many Belfast members die, and Fiona and Kerrianne have to be put under IRA protection because he poses a threat to their safety. He kills an IRA member trying to take them back, and tortures and executes another one to find Abel. He murders the adoptive family Abel was placed with. He takes Abel hostage to ensure his escape to the States, then exchanges him for another hostage whom he later kills. He tries to escape to South America through the Russian mob, but is double crossed and given up to SAMCRO, who kill him.
For a show that had Gemma try and get Wendy to kill herself via drug overdose, Neo Nazis kidnap and rape Gemma, Jimmy kidnap babies to be put up for adoption and Jax forcibly injecting Wendy with drugs, Alice Noon stands out. Her list of atrocities below sicken even the Sons and the Corrupt Cop who earlier dealt with a torture porn ring. Spoilers follow. She is Venus Van Damme's mother, and when he was Vincent and confused about his sexuality at age ten Alice tried to resolve the problem by having him repeatedly drunk and raped. From there she entered into making child pornography videos where she would have children kidnapped and raped. When Venus goes to the Sons for help she reveals her son was taken by Alice and when they go to rescue him Alice escapes with him. The Sons track them down to the child porn studio where Venus' son is drugged and about to be raped, portraits of the children that had been raped, videos taken of raped children and a camera set up to tape babies being raped. When Alice comes back she tries to emotionally destroy Venus, until Jax can't take any more and shoots her. Sobell on Television Without Pity found it Nightmare Fuel and saw fit to include phone numbers for child support services and the FBI when Alice is first discussed, that was how much she was disturbed by the episode.
Chibs also counts; originally just a background character who might get one or two lines, he came to the forefront in season two and was given a major storyline.
Beyond his Kavorka Man status onscreen, Tig seems to be emerging as a lust object for a lot of female viewers.
Two fingered compulsive masturbator Chuck Marstein reaches darkhorse status by the end of season three.
Opie. Not even billed in the opening credits at first. Eventually became an integral cog in the story arc.
Genius Bonus: The title of the episode "Capybara" counts as a mild one, since it's completely nonsensical unless you know that a capybara is an abnormally large species of rodent. The episode was about Opie being wrongly framed for acting as a ATF informant (i.e. being a "big rat"), though the title could also be seen as an allusion to Opie's innocence (a capybara looks like similar to a rat, but is a completely different species).
Jax sleeping with porn star Ima as a way to push Tara away may have made his character irredeemable to many fans. Ironic given that the entire world of SAMCRO is a study in ambiguous morality and viewers' ability to consider members of an Outlaw Motorcycle Club as anti-heroes.
AJ Weston and Ethan Zobelle when they rape and beat Gemma.
In Season 1, Gemma goes to Jax's ex-wife, recovering from an overdose in the hospital, and slips her heroin in a bible. Then she outright tells her she's human garbage and should just end it already. Another episode has Gemma holding a baby at gunpoint and threatening to "cut this baby in half" to force a nun to tell her and Jax Abel's whereabouts.
In the penultimate episode of Season 3, Stahl beats out everyone on this by murdering her lover and fellow ATF agent in cold blood and pinning the safehouse debacle on her. And then she does it again by revealing that Jax cut a deal to the club, just to mess with SAMCRO. Of course, they were in on it the entire time. It could even be argued that she crossed it in Season 1 by setting up Opie to look like a rat, knowing full well the danger it would put him in. Of course, it wasn't her fault that Opie and Donna switched vehicles.
Clay has finally crossed it by killing Piney to keep the letters a secret and may have crossed it even further by paying the cartel to kill Tara because she's read the letters. Take it another step further with Clay beating the hell out of Gemma.
Pope leaps over in his first appearance, by forcing Tig to watch as his daughter is burned alive in front of him.
Jackson Teller crossed the line by forcibly injecting heroin into his ex-wife, a recovering addict, in retaliation for her threatening to sue for custody of their son Abel.
And Gemma bashes Tara and threatens she'll be fist raped in prison for aiding Otto in his murder if she tries to leave Charming or not hand over custody of her children. She's there when the police arrest her for handing over the crucifix on the pretense of premeditation, indicating she set Tara up anyway.
Tara, of all people, crosses it when she [[spoiler:bangs her abdomen on the corner of a desk and fools nearly everyone into believing that Gemma kicked her in the stomach and made her have a miscarriage, even though she was probably never pregnant to begin with.
Your mileage STRONGLY varies with that one, as a lot of fans support Tara'a decision. And she was definitely not pregnant. That's why she had to put a bag of her own blood down her dress—to fake a miscarriage]].
Narm: Some viewers reject Tig's understated reaction to his daughter getting burnt alive.
One-Scene Wonder: In the third season, Stephen King utterly steals two scenes of one episode with his sudden inexplicable appearance. It's amazing since he barely has any lines.
Padding: Many think that season 6, with every episode being 90 minutes, is filled to the brim with this.
Tig's apparent attraction to both the dead and to livestock.
Jax and Tara getting it on about 5 feet from Agent Cohn's gently cooling body.
For those of you who enjoy chili, donot highlight this spoiler: Chuck hides a severed head inside a pot of chili so the cops won't find it, and then later serves some of the same chili to two police officers.
Trapped by Mountain Lions: Gemma (and, to a lesser extent, Tara) in Season 3. After being framed for a murder in Season 2, Gemma (oblivious to the fact that her grandson was abducted) is on the run at some hideout while Tig watches after her. Gemma breaks loose and visits her dad who's suffering from dementia. While Tig is screwing his caretaker, he gets shot in the back by Gem's father. Gemma calls Tara who stitches him up. The caretaker gets wind of Gemma being wanted and tries to alarm the police. Gemma locks her away. Gemma's father runs off, and Gemma is looking for him. Tara accidentally frees the caretaker, Gemma comes back home and accidentally kills her. They call a cleaner. Gemma brings her father to a nursing home, has a breakdown and decides to turn herself in. As she gets back to Charming, she gets a call from Maureen that Abel is in Belfast. She falls unconscious and awakens in a hospital, tied to the bed. With the help from Tara, she escapes and joins the So A on their way to Ireland. And that was only the first half of the season...
Unfortunate Implications: The shows depiction of Irish people has caught a lot of grief. Especially from Irish fans. Aside from badly inaccurate accents and slang, the fact they saw fit to cast Fake Irish actors to play such stereotypes and then actually went to film on location in Belfast doesn't help. Some Irish viewers actually stopped watching due to the story arc.
Villain Decay: A rare antihero example. In the early seasons, the Sons are little more than a brutal criminal organization, and Jax is conflicted about the club is corrupting his soul. As the seasons progress and Jax gains more control over the club, the Sons becomes more noble. By season six, the Sons are doing favors for a battered transexual and calling her "darlin'."
