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.
YMMV: Bittersweet Candy Bowl
Abandon Shipping: A large amount of Mike and Lucy shippers did this with Mike's revelation of his hatred of Lucy in "December."
Angst? What Angst?: Stunningly for a series otherwise chock full of drama: Lucy seems not to suffer from any long term effects after almost being raped. No nightmares, no PTSD, no flashbacks. She just carries on as if nothing had happened. One might argue that she's just such a badass that she didn't need any counseling, but Daisy also does not seem to suffer from any psychological trauma even though she basically stood and watched helplessly, utterly incapable of helping as her friend was pinned to the ground and groped, about to get raped.
Word of God has stated that, were she to redo the series, she would have never included the Confrontation chapter.
Archive Binge: Not the hugest, but growing. The entire archive is current working on 800 pages. If you want to comment, reading it all probably wouldn't hurt as a start. And this archive is hardly all there is to see. Booru, DA, voting in TWC, and a chatroom.
This is part of the reason Taeshi recommends new readers start at "Part 2" of the story.
Asspull: Lucy's suicide attempt, or whatever happened to her comes off as this, considering that the last time we saw her before this, she and Mike were starting to reconcile.
Base Breaker: Whoo boy. It seems that every one of the main characters have both fans who love them and fans who hate them. Most of it comes from shipping, though many of the criticisms also come from that they all seemed to have Took a Level in Jerkass somewhere throughout the series. Not even Daisy is safe from this, with some fans thinking she is extremely hypocritical and many of her actions being different from the personality she tries to present.
Darkness-Induced Audience Apathy: The complete 180 from the play arc's heartwarming recovery to the "Break Up" arc's soulcrushing, bleak tragedy has instilled this in some readers.
Die for Our Ship: An alarmingly high portion of fans have unreasonably hostile opinions of those making up the ship not their own. Such as blaming Sandy for everything, in spite of her having absolutelynothing to do with Paulo's problems, little to do with Lucy's, and nothing to do with Michael's recent behavior with Lucy, other than being his justification for it. Sandy shippers do similar with Lucy as the one to blame. It can be... disconcerting. Sometimes goes into Fan Dumb territory. The Mike x Lucy shippers seem to do it more commonly.
Draco in Leather Pants: There's a portion of the fandom who says Augustus has done absolutely nothing wrong. There is also the portion of the fans who ignore Mike's harshness toward Lucy, in spite of her facade having mostly faded already. To be fair, Lucy is no innocent on acting harsh herself.
The recurring turtle character who appears at random to trip the cast beggining in "Field Day" (although canonically he was around since the first chapter, which was published later on as a replacement for the original first chapter) seems to have grown slightly more popular. Especially on the Ask BCB Tumblr page.
Fandumb: A lot, actually. The Mike fans who treat Lucy like the Antichrist, the more extreme Lucy fans who consider her completely innocent, the Sandy haters who blame her for damn near everything, the list goes on.
Actually, Taeshi has used a collection (more of a clusterfuck, really) of anti-Mike comments (e.g. "OMG why don't you kill yourself" and other stuff that should only ever be directed at fictional characters) from the BCB forums in recent ads on other webcomic sites.
Misaimed Fandom: Certain sections of the Fandumb seem to be completely missing the point of all the deconstruction, taking sides and defending their chosen character's actions regardless of how nasty it gets.
Ron the Death Eater: There is a portion of the fandom that says Lucy is a complete and unrepentant Jerk Ass. Mike gets the exact same treatment from his detractors. There are also those who say Tess is evil, in spite of her constant efforts to avert her past status as a jerk. This has also occurred with Sandy in at least one fanfic where she is shown to be vengeful, jealous and murderous, due to the author disliking her.
