1. The bad guy is super obsessive...
Yes, life long grudges exist and people can get insanely obsessive about one thing or one group or one place, but bad guys in these action movies will literally stop at nothing, including their own deaths, to get at whomever the one person is they feel has wronged them. I mean, they will literally slaughter half their own entire team sending them in to get...one person. Logistically and financially, is that worth it? In real life, I think most real life evil warlords only really care about final end results. Did we kill all of their people? Did we destroy their entire neighborhood? Did my ultimate enemy die in all of that...okay wrap it up, we're good.
2. ...and must expose his entire plan to the hero
And while we're at it, the villain being obsessed with killing the good guy for years, finally catches him, and then wait what... sits him or her down and has a long chat about how s/he intends to kill them, how they arrived at this point, what the future holds....and then oh wait...!
3. ...just in time for someone to save the good guy
Yep, while the bad guy action villain is wasting time explaining his life story of villainy, right about then is when the good guys team bursts in, shoots and kills him, and saves the day. Barring that, the hero will figure out the plan and save the day after narrowly escaping the action baddy.
4. The impossible feat is always possible (*except permanent injury or death*)
Did the good guy have to jump over an entire canyon with his car, slide down the side of a 40 story building and walk away, fight an enemy on a moving train and no one falls off unless it's the bad guy, crash his car head on into a train but manage to jump out in time landing with only a few scratches, be fired upon by 10 people with guns and manage not a single bullet. If it's an action movie, it's possible. It does matter what it is, the good guy will escape it with nothing but flesh wounds, or a montage of him/her recovering over a few months to then magically and mystically get right back into action with no after effects from their injuries.
5. Danger is all around, but sure, let's do it
Impending death makes a lot of people do a lot of weird things, but this notion that people just jump into the sack right before or during extremely dangerous situations is clearly meant to keep some people in the movie seats. It stands to reason that you can't do it if you're dead, so maybe, just maybe a better plan would be to save yourselves and whomever first, before you do it.
6. Explosions of any kind are ridiculous
We have this natural human reaction to things that go BOOM and that's fight or flight. It is instinctual and cannot be made to go away "with practice." It makes zero sense that something could explode, especially behind you without warning, and you would not flinch or duck or move at all. The only way this is possible is if you were maybe deaf and could not hear the sound, but even a deaf person could feel that deep level of vibration that happens with intense explosions especially near by. Then there is the after burst of energy released in explosions that knocks people over. You aren't walking away head held high from an explosion 10 ft away from you! You're being hit by flames, shrapnel, the after blast, etc.
But it goes on. Every car with the slightest tap, bump, or drop from small height, just automatically explodes. The auto industry, believe it or not, works very hard to ensure that one car running into another will not automatically cause one or both cars to just explode. May very rarely catch on fire after a while or with other accelerant, but automatically explode, not so much.
7. No one is getting hurt in those collapsing buildings?
Collateral damage only exists in movies if it's a person closely related to the hero or villain. Bad guy/good guy can go on a full on rampage after each other in the city, in the jungle, at the castle, wherever, and blow up buildings, collapse houses, run people over, but it's always invisible pain and suffering and none of the destroyed cities ever talk about the intense level of damage these guys caused. They just stand there and say thank you at the end over the burning rubble.
8. Only one person can fight at a time with no weapons
Wait! There are 37 of the bad guys and only one good guy, but only one of the bad guys can fight the good guys at a time?!? What? Better still, the good guy is unarmed and all the bad guys have weapons but let's call the one martial arts guy/girl who also has no weapons to come and fight rather than just all aim the guns at once and kill him/her.
9. Do you know emergency surgery...of course you do!
Everyone including the good guy knows everything. Just got in this here plane that's going down and with the 8,000 buttons in front of them, they just figure out how to fly it. Or perhaps, they just got shot in the leg, their random friend can sit them down, pour some alcohol on the wound and just retrieve the bullet with a pen knife without hitting another artery and having them bleed out. Or perhaps its the enemies gun or other weapon the good guy just found, and knows how to operate despite it being totally different from any weapon they've previously used throughout their training or the entire film. Or, my favorite, the hero always pretends that he or she doesn't know the enemies language, but for that one scene, they surprise them by knowing everything they are saying and say something back in their native tongue.
10. Convenience is convenient
Right when the hero/villain runs to the elevator, it's right on their floor because they pushed the button. Gun runs out of bullets, the next one, happens to have a new clip fully loaded. Right when they are falling down a cliff, there is the tree branch to grab on that perfectly supports their falling weight. Right as they run out of the building, there is a car/bike/someone waiting that they can easily get to, or start, and drive away in. Right in the middle of the car chase, when the one car gets trashed, the hero/bad guy can easily jump to the next and not die.
Action Movie Dishonorable Mentions
-you can punch anybody and they will go down unconscious immediately after that one punch
-if any character mentions any kind of family or we see any family in the movie, they WILL be kidnapped or murdered
-whenever the main character knows its a trap, they go in anyway
-Sure, the hero is shot in the leg and bleeding everywhere and doesn't wince or shed a single tear, but let someone pour a bit of rubbing alcohol on the injury and they are wincing in horrendous pain
-if anyone throws any type of knife, it hits the target perfectly square on
-if you are an action movie minority--you either will be killed off as soon as possible, know martial arts, or know some mystical magical power handed down through generations
-Police never question the hero no matter what he or she does. Sure they murdered those 18 people and caused a crap ton of damage, but that's okay, because they're the hero no questions asked
-When the good guy needs to escape his ropes or cuffs, there is always a key/sharp edge to help them nearby
