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.
Anvilicious: Willis doesn't tend to be very subtle about his points.
Base Breaker: Amber/Mike. One third thinks they work together, one third thinks someone's emotionally abusing someonenote And given Amber starting the relationship with blackmail and Mike...being Mike, this group is split as well or that they're just plain not right for each other, and one third thinks Mike's just waiting for the right moment to give Amber maximum suffering.
Ethan's collecting habit. Many in-depth discussions (read: arguements) were had over whether Drew is right and it's a harmful addiction, or whether it's an innocent hobby and Drew is being unreasonable.
Fuckface the iguana, despite simply sitting around with one facial expression. (This is usually in contrast to Malaya, who is less popular.)
Arnold, one of Ken & Malaya's roommates, also gets a bit of this. His appearances in two strips — telling Malaya to get a job in the first and telling Ken to "stop barking up the bitch tree" in the second — were enough to make him far more popular than either of them.
Faz and Ninja Rick, because they're both absolutely hilarious.
Lucy is VERY quickly being embraced by the fans, both for her stance on superheroines and her chewing out of Malaya.
Then, just as if deliberately fucking with the fans, Willis had Robin and Joe start making out, an event that revealed that Leslie and Robin still had it bad for each other but each also thought that the other had moved on. GRRRR. Damn you, Willis!
When Robin is elected to Congress, she insists on wearing her sombrero while in session. Fast forward to November 2010, and Frederica Wilson.
It's either this or Harsher in Hindsight, but in April of 2006, a strip called Bingo was released, which was about Ethan showing a Internet argument-losing bingo featuring overused and ilogical internet arguments, and one of these arguments was "Claiming to represent the fandom as a whole". Then, five years later, in December 2, which strip was released? The False Equivalence strip. Whoops.
Internet Backdraft: Mike and Amber's relationship, between those who think that if he didn't really want it (whether because it's the relationship itself he wants or because he's setting her up for a fall) there's no way she'd be able to keep a hold on him or that he's such a bastard that he deserves whatever he gets, and those who see Amber as using blackmail to rape him and think that she crossed the Moral Event Horizon when she forced him to start dating her and keeps going further over it the longer she keeps it up. Recent events have not helped.
Any strip dealing with real life behaviors, be they stupid toy arguments or social issues, will inevitably get a hostile reaction from people insisting that the situation described is either nonexistent or a non-issue and accusing Willis of somehow forcing his opinions on others.
Mike IS this trope. He's capable of planning and executing extremely convoluted plans for the sole reason of pissing someone off and despite that most of the cast considers him a friend, with Amber and Ethan even up to a point of becoming a subject of desire. In fact, the above example is the only time his plan ends up not having the effect he expected, and even then due to actually trying to achieve something he thinks is good for her.
"whoreswhoreswhores". So pervasive is this meme that as soon as the Miller-directed The Spirit teaser trailer came out, most of the comments on YouTube were along the lines of "whores". The teaser didn't feature any actual whorelike behavior, but the actual trailer did. By then everyone had used up all their ammo.
A meta one. Whenever something happens in the comics that the fans don't like, they will post "DAMN YOU WILLIS!" in response. Became pervasive enough that Willis' Twitter account is named "damnyouwillis".
The Scrappy: Malaya for some. Some find her grating and annoying and hate her constant bitching while contributing nothing. The fact that she was created as the result of a fan's bitching doesn't help matters.
It really says something when her pet iguana, Fuckface, is a vastly more popular character despite doing nothing but sitting around with the same facial expression.
Unfortunate Implications: Or maybe just hypocrisy, but Willis often makes points about just how terrible and oppressive and just plain mean straight white males are by putting his own arguments in the mouths of minorities (gay men, black women, etc.). Since he is himself a straight white man, it could easily be considered appropriation, where he makes use of the struggles and trials of others to make his own points.
On the point of his hypocrisy, many people likes to add this to the list.
This strip in particular seems to have raised concerns as a commenter posting constructive criticism was told in no short order "Get off my website."
He later shut down comments when other people kept questioning the strip's quality.
Villain Decay: Mike is getting it hard, leaving behind the central concept that he "just was" as he was.
Although Mike was generally the flattest character in the Walkyverse for comedypurposes, he did have a few hints of depth every now and then, especially in his relationship with Dina. For example, this comment to Joe suggested that Mike may have actually cared for Dina and caused a firestorm of debate about Mike's character when the strip first aired.
Faz even moreso. He has lost any semblance of power and has been so thoroughly defanged that he can no longer plausibly threaten Amber or Ethan - he's just a Butt Monkey now.
He's Back. Mike's marriage proposal to Amber is almost certainly his Crowning Moment of...Being Mike. A whole year ago he found out that Jacob had a crush on Amber, as well as a sex adiction. He had also promised that when Amber's mom Stacy came to visit, he wouldn't bang her. So he switched the numbers of their (his and Jacob's) appartments and stole Stacy's phone so that when she came back to look for it, she would end up knocking on the door of Jacob and get seduced by him. Then Mike recorded the resulting sounds and edited them into an actual marriage proposal. Magnificent Bastard indeed.
But he only did that because he loved her enough to try and get her to break up with him so she'd end up with something better. He had to get drunk (and turn into Nice!Mike) to do it because Asshole!Mike is too selfish to let her go.
