A Pet Peeve in Movies

Nothing in fiction (especially movies) annoys me more than when the hero gets the jump on the bad guy and knocks him out, then grabs the girl and says "Let's go!" 

Let's go? Let's go and leave the psychopath who wants me dead alive and well to finish the job? 

The hell with that. You've got him down, now cut his throat. #EndTheThreat
