Turn offs I don't like about some movies:
The heroes are completely incapable of doing any of the action so bad it's laughable.
A plot that goes nowhere.
Being preached to like I'm some sort of retard.
Fillers in the story to stretch out the two hour limit like endless shot of the scenery.
An ending that doesn't complete the plot.
Evil or stupid main characters that I can not stand to be in the same room and I'm expected to spend money and time.
Ridiculous time warps such as a a gun or equipment that wasn't used during that era.
"Strong" actors that just rude, inconsiderate and bullies.
Actors surrounded by plot armor.
