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.
First Installment Wins: Any trouble digesting the ridiculata of the latter seasons will either be soothed or completely exacerbated by the dramatic superiority of pretty much any episode from the first three.
Harsher in Hindsight: The death of Bette's father was followed soon after by the death of the actor, veteran thespian and civil rights leader Ossie Davis. (Those pictures from the funeral with MLK and Bill Clinton weren't Photoshopped.)
Jumped the Shark: The exact timing is debatable. Some fans think this happened after Season 3, or even earlier, while others think that Season 4 and beyond was when the show grew its beard.
Moral Event Horizon: Once they learned that he'd rigged the entire house with surveillance cameras so he could turn the intimate details of his roomates' personal lives into fodder for his next documentary, there was no way in Hell the viewers were ever going to forgive Mark. (Which is probably why he was Put on a Bus between Seasons 2 and 3.)
For some, Jenny crossed this when she repeatedly and cannivingly mocking Max for being transgendered, repeatedly calling him "she" and a "mom." She pretends to be confused as to why he is upset. Especially the scene where they celebrate Max being pregnant with the Willy Wonka-themed party. Jenny acted in such a disgusting manner- this was one of the reasons that Max ended up having a severe anxiety attack.
Most Annoying Sound: For some, Alice's voice. In the show, Alice for some reason decided to raise the pitch of her voice significantly and make it sound more nasally. She sounded relatively normal early on, but her voice sounds like a nasally chipmunk in later episodes.
Pandering To ThePeriphery Demographic: The show was supposedly aimed at a female audience. However, it garnered a very large straight male fanbase mainly through extensive sex scenes, reducing gay guys to background extras, making one of the girls bisexual (which ensured a straight guy would participate from time to time) and making straight guys prominent in the supporting cast. Actual lesbians didn't miss that and often denounced the whole show because of the blatant pandering.
The Scrappy: Jenny, to somemany almost all viewers. There wasn't a viewer who didn't cringe every time Tonya opened her mouth.
Niki. The party girl closeted lesbian actress who uses a beard and who dates older women. She was based on Lindsay Lohan. This was confirmed as fact by the actress, and the writer Angela Robinson (Who is a lesbian and worked with Lindsay so there may be Reality Subtext there)
Alice's reaction to the death was, for some, even more agonizing than the death itself.
That whole scene was terrible. Alice is in a gift shop, and she finds a little plushie of a potted daisy that sings "You Are My Sunshine." Any genre savvy troper knows that this song is bad news in works of fiction. Alice buys the plushie for Dana, and goes to the hospital to see her. When she sees that Dana has just died, Alice slumps over onto the floor and just bawls and wails loudly, her face contorted in horrible agony. She drops the little plushie and it sings that song.
The fact that a gif of the following scene has reached Memetic Mutation-status on Tumblr actually kind of makes it worse, in a way...
