I know what you mean about the good guys winning. Let the bad guys win for once.
I hate it when the bad guy has the good guy at gunpoint and then proceeds to babble on and on about how he "waited a long time for this moment" or "I am going to enjoy killing you" While this moron is talking, it gives the good guy enough time to grab the gun or allow his buddy to show up and kill the bad guy. Why dont the bad guy just shoot the guy and then dance on his grave and talk trash AFTER the guy is dead.
Another thing I hate is when some moron is being chased by a serial killer/monster and they hit it in the head and knock it out and then walk away thinking it is over. You know it aint over and the killer/monter will wake up and come back after them. If that was me I would knock it out then proceed to bash its head in until the brains oozed out then break the legs and arms and crush its chest. I am going to make sure the thing is dead before I turn my back on it. Even if it dont die, it wont be in no shape to pursue me through the woods.
That reminds me of a brilliant quote from Terry Pratchett's Discworld:
pray you never face a good man...he'll kill you with hardly a word.
Although I do enjoy a good monologue, if it is artistically done.
