And in 2017, we saw Jackie Chan (who is 64 years old but at least still looks like he gets carded in bars) kick some butt in The Foreigner after his daughter dies in a terrorist attack. While he can't bring his daughter back, he does get his ass-kicking ability back, and isn't that almost as good?

But right now, the king of this character type has to be Keanu Reeves, the world's most badass action star who also needs a yearly prostate exam. As John Wick, he has tumbled through carnage after carnage, renewing his dusty hitman union card after some mobsters kill his greatest love: a puppy.

Of course, this trend started with the Taken series, wherein Liam Neeson shoots his way through every European ethnicity to un-kidnap an assortment of helpless women. Neeson is still riding that violent old man wave to the bank, having starred in old-em-ups like Non-Stop, A Walk Among The Tombstones. and most recently The Commuter, where this time he has to use his old hands to kill young'uns on a train. You know, trains, that hip new mode of transportation? Maybe in the next one, Neeson can be called in to shoot up a hostage situation in a bingo parlor.

It's not hard to see why these movies are so popular. For one, unlike other schlocky action movies, they tend to attract big actors, as we now have a whole bunch of aging movie stars eager for one last action-packed hurrah before they spend the rest of their careers playing someone's sassy granddad. But it's also because Hollywood clearly has found a lucrative new demographic. By portraying a bunch of sad and lonely old dudes who did shitty things when they were younger but are suddenly needed again to fix things, Hollywood has also found a shortcut to the most lucrative, still-DVD-buying demographic of them all: bitter divorced dads.

And last but certainly not least, there's Thanos, who knows the Universe has finite resources, and yet we all won't stop breeding. So he randomly selects half of everyone and turns them to dust. What a devious and harsh scheme, reducing humanity's population to what it was ... 50 years ago. Best keep those snapping fingers limber, Thanos, because you're going to need to do this every half-century or so.

Columbia PicturesNot even villains were safe.

Danny McBride's character even says John Denver's name out loud in the scene, so if you thought it was weird that John Denver was popular in 2017, apparently he's still as hot as ever in 2104. But let's get back to the present -- specifically, the time of Logan Lucky, in which Channing Tatum, playing a blue-collar Danny Ocean, rushes through his daring heist so can get home in time to hear his daughter sing the Denver classic at a pageant.

Tatum must be sick of that song by now, because that wasn't the only one of his movies it featured in that year. Let's go back to the Kingsman series. In The Golden Circle, a character actually sings the song aloud to play himself off as he makes a Star Wars-worthy heroic sacrifice, in the process proving yet again that everything's better if sung in a Scottish accent. Take it away, Mark Strong!

And the Denver train doesn't appear to be slowing down. In 2018, "Take Me Home, Country Roads" has already appeared in the latest Fallout game trailer, teasing its possible location. So why so much John Denver? It might be because of one man: Brian L. Schwartz, who now manages Denver's estate. He was allegedly hired by Denver's children to try to get his music back into the public eye. By all accounts, the dude's doing a bang-up job.

Well it's 2018 now, aka "the worst possible future," and we finally are rid of that repetitive color scheme. Now everything's a dim and depressing violet and blue! How diverse!

Studio CanalLook how sad Nick Hoult is.

Actually, some consider it diverse indeed. The color scheme has been called "bisexual lighting" after the colors of the bisexual pride flag. It's become kind of an internet meme to suggest that the lighting scheme is used to represent bisexuality itself. There are definitely examples of that (more commonly in TV and music videos than in movies), but what it's mostly used for is to showcase urban sleaze, like in Blade Runner 2049.

Warner BrosNot a face that screams "I'm embracing my bisexuality."

Unlike orange and teal, violet and blue tends to be used to convey a specific atmosphere -- namely seedy, futuristic inner-city nightlife. If you want to show a rave where the chances of getting laid and getting shot are about 50/50, the color of '80s neon signs is the way to go. Here we see it in a seedy part of town in John Wick 2 ...

Broad Green PicturesAccurately replicated in the porn version, Night Of D-Cups.

... oh, and a seedy part of town in Logan:

And of course, there's literally everywhere in Ready Player One, a movie that bleeds '80s neon when you cut it.

Warner Bros. PicturesAnd screams John Hughes quotes when you twist the knife.

If someone's about to cry in a nightclub, don't even crack that Pantone color wheel; you already know what to do. And if your protagonist goes to a strip club to have an emotional breakdown, are you going to light that shit with lilac and summer lime?! Heck no. Violet and blue has been the law since at least Closer in 2004.

Columbia Pictures"Cut! Dammit, who gave Natalie a pink wig?"

Which does raise the question: What is the real origin of this seemingly universal creative decision? Our theory is that there's a really depressing strip club with this color scheme somewhere in Hollywood, and every cinematographer secretly picks up shifts there to make ends meet. And if you know where that is, please let us know. We really want to meet Roger Deakins.
