When one character who's an expert in some field stops to explain the most basic concepts to another character who's also an expert on the same subject.

When the movie calls for an ugly guy, they get an ugly guy. When the movie calls for an ugly girl, they get a sexy girl and dress her in dumpy clothes.

Fake snow and low temperatures that never matter. Like in Game of Thrones where nobody wore a goddamn hat on the wall. I was watching “his dark materials” the other day and I almost started to applaud when heroes actually got dressed for the cold weather. Also, Russia in snow. We have summer too.

When the trailers reveal most of the plot.

When it's very obvious when someone isn't actually having a conversation on the phone. They just say their lines without giving enough pause for the other person to respond. I also hate when you're supposed to be looking at security footage but it's clearly just a previous shot that's had a filter put over it.

When there is a timer and it takes longer to count down than the time that was called/shown. It drives me crazy. Generic example, 50 seconds until a bomb explodes. Dialogue for 30 seconds. Timer is showing 30 seconds left. More dialogue for 40 seconds. Timer is at 5 seconds. Quick one-liner, bomb defused with one second to go.

The very strong/smart main villain turning weak/dumb in the end fight so the heroes can win.

"there's no time... save yourself!" when there's clearly ample amount of time for both characters to get to safety. made even worse by the fact that they usually waste a minute or more arguing about it, saying teary-eyed goodbyes, and making out before character 1 finally gets up and leaves

Having to constantly have my remote in hand to turn down the absurdly loud action scene, to then have to crank the volume for the next dialogue that is far too low.

Overused female tropes. The angry black woman, plus sized women always being loud and clumsy, and of course, the manic pixie dream girl. This isn't some feminist soapbox, it's just lazy and uninspired writing.

When all you have to do is beat the boss and the entire army just collapses. Pretty much every alien and robot-using invasion has this hive concept.

Maybe not 100%, but close to it. Fight scenes where someone make a big blow(usually the villain), but instead of finishing the deal by smashing the brains out they start talking, bragging or some other cocky sh*t. And woops, the fight is back on like nothing happened..

Action scenes with lots and lots of cuts, that make it obvious (or appear like) the actors can't do the fight choreography.

It was a dream.

Insane plot armor. It’s okay for a main character to die.

Badly implemented product placement. Product placement itself doesn't bother me. If there's a character driving a Toyota, or eating a Pizza Hut pizza, I don't care. If there's a pointless shot in the movie that shows the f**king Bud Light logo for 10 seconds, I mind

When the villain is always a few steps ahead of the hero for no reason. Somehow, the villain has managed to predict every move the hero and is going to make.

Forced moral messages, like really forced, the kind of messages that feel so unnatural that nothing can justify

The bit where hackers take 20 seconds of furious typing to disable a countries infrastructure

When the premise for a major conflict in the movie is something that any sane person would have just said "oh no there's a misunderstanding" and they all have a laugh and go on with their days... But instead it turns into some convoluted drama.

When things explode for no reason. “Vehicle had minor collision or simply rolls over and spontaneously explodes”

Unnecessary love scenes where the main character and a side character fall in love just cause, despite having known each other for like five minutes.

Forced romance subplots in a non-romance based movie. A BaBY A hero I'm supposed to root for because???? They're the protagonist??? The villain doesn't have a reason, they're just Random and CRaZy

Bad exposition dialogue "As the son of [GOODPERSON] you shouldn't do drugs here.." "Kleetus, you're my [SIBLING]. I've taken care of you since [PARENT] died and [OTHERPARENT] left us. Remember how we would play at [HOMEPLACE] but you had to move away because [JOB]?" "Well, well, well, Micky, the [MOSTWANTEDCRIMINAL], at my doorstep. What's the matter, didn't your [PARENT] cut you any more slack, so you've traveled here from [PLACE] to see your [SIBLING], my [SPOUSE]?"

When there’s a 20+ year age gap between the leading actor and actress and it’s not addressed in the movie, especially when the movie pretends like they’re around the same age. “We’re both experienced, leading scientists in our fields, even though I look like a grizzled war veteran and you’re fresh off the set of High School Musical.”

"video games" in movies that are set after 1988 yet they all sound like pacman or space invaders.

When bad guys have no redeemable qualities. It’s too convenient and unrealistic.

When they explain the plans like...to an 8 year old. I like movies where things just happen.

Teenagers who sound like screenwriters trying to sound cool. Never in the history of humanity have two 15 year olds randomly recited 18th century poetry to each other on the day they met, and all those snarky remarks makes the kids sound insufferable and annoying a lot more than clever. Also notice that somehow every clever 15 y.o. always listens to music that was huge when the screenwriter was growing up, never something that is... you know... listened to by 15 year olds... as if there was no good music around presently. PS. Also the whole sarcastic genius with no social clues...yes we get it Dr. House was a hit 20 years ago, now can we get Cumberbatch to play any other freaking role?

Twist villains where the bad guy is revealed in the last 10 minutes of the movie.
