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.
They divided fans more during the series finale, when Liam and Amy have sex, which many thought drudged back up a terrible lesbian cliche.
Given Amy has not, as of the season 1 finale, identified herself as a lesbian, so the argument can still be made she's figuring things out or that it was simply an act of revenge against Karma. In season 2 she does experience some desitre for a guy from Brazil but seems to prefer women overall.
Liam, both for shipping reasons and for those who are divided as interpreting him as a Jerk with a Heart of Gold or simply a Satellite Character who brings up some sexist cliches about women always scheming to get The Guy Everybody Wants.
Shane gets this too, for those who think he crossed a Moral Event Horizon when he "outed" Karma and Amy as lesbians in front of their classmates without their consent.
Fan-Preferred Couple: The show seems to be trying to sell Karma/Liam as much as Karma/Amy. Pretty much no one is rooting for the first ship. So far every single fanfic is Karmy and Katie Stevens and Rita Volk seem to ship it themselves. Those that do sometimes pair Liam with Shane.
Fridge Brilliance: Bruce seems much more accepting of Amy being gay than Farrah. It makes sense in Season 2 when it's revealed that Lauren is intersexed
Ho Yay: Liam and Shane experience a few instances of it, such as Shane leaning his head on Liam's shoulder.
Hollywood Homely: Dialogue suggests that Amy is supposed to be plain and unconcerned with her appearance; everyone (including Amy herself) automatically peg her as "the butch one" in her relationship with Karma.
Unconcerned with her appearance, yes. Plain, no. When she goes to the lesbian bar, all the girls she flirts seem very receptive to her advances - until she screws it up by being obnoxious or running away.
Iron Woobie: Yes, Lauren isn't the nicest of persons, but she simply hasn't caught many breaks and she's right in that another school, she'd be a queen. She acts out, yes, but people forget that shes been uprooted from her home, she has no real friends, there's no one at her high school that she can connect with (save Shane, and she's pointed out that neither of them are very nice people). Still, she's amazing at helping with Farrah's wedding, she empathizes with Amy after their mutual breakups, she manages to maintain a friendship with Pablo (who she actually attempts to protects from Shane's dating style), and she never told their parents about Amy & Karma's entire scheme. (Yes, she tried to bust them at school, but it wasn't personal.) On top of everything, she was born intersexed
Les Yay: Leads to Karma and Amy being mistaken for lesbians in the first place.
No Such Thing as Bad Publicity: The criticism from LGBT websites is one of the main reasons people know about it. Many of the LGB Ts who watched the show to see what the fuss was about ended up falling in love with the show and Amy in particular.
Rescued from the Scrappy Heap: Some would say Liam, as he evolved into a much more rounded and sympathetic character by the end of season one and was no longer just a Satellite Love Interest who just Wanted To Hook Up With A Lesbian, as he grows to truly care for Karma even with his and Amy's alcohol-fueled betrayal. Also gets a lot less Die for Our Ship treatment as Amy/Reagan has been widely embraced by the fandom.
Lauren, too, as she revealed more character depths than being the suppressed Alpha Bitch and can be a caring individual beneath the harsh Ice Queen exterior. The canon Theo/Lauren also proved to be very popular, that is until Theo's secret is revealed...
Ron the Death Eater: There's a fair portion of the fandom who villainize Karma for practically everything that she does.
Karma was moving into this territory for a sizable part of the fanbase in season 2, as possible Flanderization has made her even more self-centered and melodromatic than before, and some think she's intentionally undermining Amy's relationship with Reagan because she's no longer the sole focal point of Amy's world. On the other hand, some would justify Amy's increasing coldness toward Karma after getting together with Reagan and the whole thing with Liam is partial justification for Karma's modest exaggerations in character. Gained more sympathy towards the end of Season 2 after Amy and Liam's secret was revealed.
Ship-to-Ship Combat: Although dominated by Karmy, there are those that hold out hope for Kiam (and even a few Lamy (Liam and Amy) shippers after the first season finale.)
Karmy now has a new enemy in Reamy, due to Amy getting a girlfriend of her own in season 2.
Some Anvils Need to Be Dropped: Shane (reluctantly) allows Duke to keep quiet about his relationship with him while he searchs for MMA sponsers. However, when Duke ends up striking a deal with Cluck-n-go (an obvious expy of the religious fast food chain Chick-fil-a), despite their notoriously homophobic leanings, Shane refuses to go along with it and ultimately severs his relationship with Duke.
It does seem odd he wouldn't be suspicious of Karma being straight or at the least bisexual when she spends a lot of energy either explicitly flirting or even trying to sleep with him... Liam definitely doesn't seem to be the sharpest tool in the shed.
