I am writing a thriller, and have a question as to if this type of scenario is bad for the genre or not. Basically in the climax, when the hero has no hope of getting the villain and it's a dead end, in some thrillers, another character will come in and have something, whether it's an object or a piece of information, that will bring down the villain and resolve the conflict. But is it bad when stories have a minor character come in with something to resolve the conflict rather than the MC doing it, on his/her own? Since I am into writing screenplays, I use movies a lot for examples, if that's okay. In the movie The Departed (2006) for example: SPOILER AHEAD The hero (Leonardo Dicaprio), is hopeless in getting the villain arrested, and thinks he is going to die, at a dead end. Then just when things couldn't get any worse, the mob boss's lawyer calls him and gives him evidence to bring down the villain. This puts the hero in an advantage and gives him the upper hand, when he was at a hopeless end before. So if you think about it, the lawyer, who never has any screentime, and was just verbally mentioned in the climax, is the real hero of the story, since his evidence that he turns over, is what is needed to resolve the conflict. Nothing the hero does is able to, but the minor character can. I am wondering, when it comes to stories, is that a bad idea to do it that way? If you find that your MC is trapped and painted into a corner, is it okay for a minor character to have the answer, and show up with it, to resolve the conflict, rather than the hero, using his own brain and ability to do so? The movie is a best picture winner, so a lot of people obviously do not have a problem with it there, but what do you think?
