*loud internal screaming*

The protagonist whose spent the entire movie mowing down mooks and goons left and right, who finally gets the upper hand on the truly evil overlord of the whole operation, and then pulls this BS:

"No, I can't kill you. Because that would make me as bad as you."

"One character has something important..."

One character has something important to tell another character but they don't want to listen and they leave which creates confusion and chaos making the movie way longer than it should be if the other person just would've shut up and listened.

"Bad guys..."

Bad guys with machine guns rarely hit anyone, but a good guy with a handgun can make impossible shots.

"It's like we all..."

Hitting someone on the head knocks them out for a few minutes, rather than causing concussion, brain damage, internal or external bleeding, or just severe pain. It's like we all have a big snooze button on the back of our heads.

"Not only..."

Prosecutors introducing "surprise" evidence or surprise witnesses during the trial.

Not only will it be a mistrial, but you will likely lose your law license if you try to pull that crap in real life.
