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: Kevin And Kell
Anvilicious — Comic about the equivalent of an interracial couple. So, yeah, it's gonna happen.
Archive Binge/Archive Panic — Going back to 1995, this is one of the longest-running webcomics with over 5000 strips and still counting. Nearly OVER 15 years of DAILY strips.... You don't need to read the full archive to understand the newer strips but you have to read them if you want to get the full story.
Ass Pull: the recent "Kevin getting a recall election," storyline, starting here. The whole thing is built up so that all rabbits are divided on how the ears are portrayed- ears up is one side, and ears down is the other. Both sides hate each other with the same vitriol as opposing political viewpoints. Kevin has one ear up and one ear down. So Bill Holbrook has the option of either going into a storyline that delves into politics and Kevin struggling to find compromise and balance in the system... or he could have every rabbit in the world suddenly have ears like Kevin with absolutely no explanation, getting him re-elected and preserving the Status Quo. Guess which one Holbrook went with.
Boring Invincible Hero — One review suggests that the main characters have become this, not in fighting style but that they will always succeed at whatever they do somehow. It surmises that this is because Holbrook has fallen in love with the characters and cannot bear to make them unhappy... which would seem to be supported by his extreme focus on the strip, even over his more profitable comics and endeavors.
Critical Research Failure — Lindesfarne's squick over Human!Martha's sweat. Several animal species perspire (including primates). Particularly egregious given that Lindesfarne is a biologist and should've already have known what sweat was.
In this comic, Coney is losing marks for not sharing her meals by regurgitating them. Most people would find this funny due to the idea of the rabbit being greedy, but the thing is, rabbits are physically unable to vomit, meaning that she literally cannot share her meals by regurgitating them.
Also the mole scientist named Avagadro: in chemistry, Avagadro's Number is the number of molecules in a mole.
Related to this, any references to diapering flying hedgehogs.
Internet Backdraft — The entire Danielle saga caused massive flame wars on the Kevin and Kell mailing list. Even Danielle making a one shot appearance will send them into a furor. This fan reaction is credited for the strip abandoning the long-running, complicated serial plots it had relied on for much of its existence.
It Was His Sled — The Great Bird Conspiracy, that they ran the world until they gave it up.
Getting to this trope is that Lindesfarne and Danielle are former humans.
Jumped the Shark — It seemed like the comic decreased in quality when humans were introduced into the story.
Misaimed Fandom — Surprisingly, the comic really does make some fans appreciate the world we live in a lot more. (Mostly because Real Life could be a hell of a lot worse.)
Plus, apparently it's illegal to kill someone unless you eat them afterwards.
Strangled by the Red String — Rhonda dumps Edgar, a character she had been dating exclusively for much of her history in the strip, for Quinn, a character the readers have just met, has had no build-up at all, and its supposed to be "true love". Even more distressing is that this is also Rhonda's final storyline, as the marriage served to put her on a bus.
They Wasted a Perfectly Good Plot — Lindesfarne and Fenton's wedding, which was the culmination of roughly a decade of the strip's history, should have been an occasion to show off the entire diverse cast over the years and highlight the much-anticipated union of two characters who had been dating since the strip's earliest years. Instead, the entire thing was derailed to introduce and glorify Fenton's mother, Desdemona, a brand-new character, and the entire plot was hijacked to focus on the bigotry she faced as a vampire bat. Not shockingly, this was also the first time vampire bats or bigotry against them was revealed. While a handful of long-unseen characters poked their heads in once or twice, the majority of the plot was focused on Desdemona and nothing else (not even how her son might take the news that his mother had essentially lied to him his entire life). For one more kick in the pants, you're twice as likely to see Desdemona in a strip now than either Fenton or Lindesfarne.
