"Well when you have all these people who think murder is amoral, killing is bad, yadda yadda praise jesus and democracy yadda yadda then it's no surprise they don't like the characters. They believe these are bad people. They are scared of such people. If they like anything about the characters they rationalize it by saying Mickey and Mal are victims, are "mentally unstable" or such, and they believe these characters need our pity and our help to be good christians. These people are washed over in pity in the second half when Mickey and Mal are having regrets about some of their killing since they see this as a light towards their moral system (which they usually ignorantly think is the only possible moral system), and then they're probably grief-stricken and angry at the ending of the film.
We who are their opposite, rather enjoy the characters, recognize their weaknesses, and are a bit happy that they succeeded in the end, even though it's far from a perfect story for them, we are living in far from a perfect world. And given the society they are set in, this is a very powerful story."
There is a middle ground, y'know. I definitely think society and the culture that people like Wayne Gale propagate are worse and do a lot more damage in the long run. They're the real villains of the film. I'm not a Christian and don't think democracy is always the best system. But does that mean I like or admire Mickey and Mallory? Of course not. In fact, I think some of the best satire in the film are the idiot teenagers who are interviewed and love Mickey and Mallory, yet still think murder is wrong.
To me, Mickey and Mallory Knox are the ultimate extrapolation of our society and our values. Stone has said the film is a satire on how the media looks at serial killers, condemning them while giving them a lot of attention and ultimately promoting the same morals. In a society where logic, reason and scientific skepticism are looked down upon, Mickey and Mallory are passionate in everything they do. Mickey spouts some pseudo-philosophical crap about how he's evolved, failing to understand true Darwinian evolution (with misunderstanding evolution being a key American trademark) and instead echoing the Social Dawinism talk They think they're the ultimate rebels, but of course they do. One of the most powerful things are society has is to integrate the rebels as part of the system. The system isn't being destroyed because of Mickey and Mallory; the system thrives on Mickey and Mallory. The bloated, mindless, act-first-think-later, capitalist machine loves including them.
But does this mean I like Mickey and Mallory? *beep* no! I hate the shallow, passion-based society, so if they're the ultimate extrapolation of it, I'm not going to like them. It's this culture of dog-eat-dog, competition is good whether it's business or politics or sport, let the strong take what they need and *beep* the weak, etc. that leads someone to commit the ultimate intellectual hypocrisy, which is to take the life of someone else while leaving your own existence alone. America does it all the *beep* time, they're just called wars. In a way, I have to admire Mickey and Mallory for at least not thinking they're great people like Gale, but really, they're all cogs in the same machine, and their philosophies and worldview are not in opposition to the society they're from, but reveling in it. And if you're like me and *beep* hate that society with all your heart, you can't find Mickey and Mallory Knox likable.
On a completely personal level, their constant PDA and lovefest just got on my nerves, but that happens with real life couples who aren't mass murderers either.
