Dumb fucking villains, it's just bad writing when the bad guy has the hero right where he wants him and can execute him right then and there with absolutely no reason to keep him alive yet he doesn't he just stalls like a complete pussy then leaves it in someone elses hands who inevitably gets their neck snapped by the hero.
Another one I hate when the bad guy tries to play the morality card on the hero "You'll be as bad as me" after the hero has already had to blast his way through dozens of faceless goons, I mean what the fuck? If anything feel bad for the goons they're just following orders of this asshole!
Forced romance sub plot, It's not needed, it only makes realtionships look stupid and it is usually very sexist, how the male lead is rewarded with hot female trophy for all his troubles.
War movies about Heroes. I don't mean like the people who fought in WW2 but the ones that imply ONE MAN on the battlefield changes the course of an entire war, I'm pretty sure generals/strategists are the guys who change the course of wars.
Deus Ex Machina, a case of lazy/convenient writing, sometimes I allow it but other times it's completely obvious, for example every Harry Potter book/film could/should have been named "Harry Potter and the Deus Ex Machina"
The kid, you know the one, you liked a film then the sequel/prequel has a child actor you just have to hate.
The thriller that uses the plot twist/device someone else already did. I'm going to drag in Heavy Rain as the example here, the gold watch is mentioned right at the damn start of the game and everyone who has seen Speed knows what that means. Also the whole "How do children disappear in public" angle, well Persona 4 covered that one, it's a fucking cop!
"THE WEAPON/SUPER MOVE" This is more common in anime but I hate it when some kind of powerful weapon or technique is revealed and they spend half an epsiode explaining it before they use it I mean Christ are they trying to SELL me the fucking gun or what?
