I have been writing a screenplay for a while now, but I have had no idea how to end it with an ending that works. Basically it's about a serial rapist/killer villain who has been going around doing his thing, and the MC who brings him down. I have suggested quite a few different endings, over the past year, but I have been told each time, that none of them work, because they are too 'implausible', as it was put. They are just too ridiculous. A few writers told me something that I keep thinking about and they say that a ridiculous story works as long as you create suspension of disbelief. How does one do that, as oppose to having just a ridiculous story in comparison though? Basically for my ending I am having trouble with an idea to get the villain caught or bring him to his downfall. Since I am writing a screenplay I tend to use a lot of movies as examples to compare, rather than books, if that's okay. Tonight I rewatched the movie Confession of Murder. I'll spoil the movie to ask this question when it comes to writing: SPOILER In that movie, a serial killer gets away with all his murders, because his statute of limitations has expired. In the movie, set in South Korea, it's established that in that country they have a statute of limitations, where if you are not caught for your murder within 15 years, you cannot be charged after. The main character is bent on finding out who the serial killer is and getting revenge, since the serial killer killed his mother. So the MC creates a whole new fake identity and gets plastic surgery to become a new person with a different look. He also creates a false birth certificate and the works to become a made up identity. He then pretends to be the serial killer and writes a book on all his murders, and how he got away with it because of the statute of limitations expiring. He then sells the book with great success and becomes a nation wide celebrity and millionaire. This causes the real serial killer to become enraged with jealousy over the MC taking credit for his work, and getting a lot of national publicity over it. So the villain then comes forth and tells the media and the world, that the MC is a fraud taking credit for his work and that he is the real killer. He also offers the public proof, so they will believe him. This is what the MC's plan was. To get the real killer jealous to get him to come forth and flush him out, so he can find out who he is, and can then get his revenge on him. Now the MC's plan was a long shot. I mean if you go through all that trouble of getting plastic surgery, coming up with a new identity, writing a book and becoming a millionaire celebrity by selling it, on the hopes of making the killer jealous enough to reveal himself, is a huge long shot. It's a huge long shot that probably would not likely work at all, but the killer fell for it, and the MC's far fetched plan worked perfectly in the end. So how can I write an story like that where the MC has a ridiculous plan, that probably wouldn't work, but does, so the audience buys it? I am wondering what's the trick to creating suspension of disbelief, so the audience will believe it, as oppose to not and just having a ridiculous story in comparison. A lot of times when I show my work to other readers, the readers say that that character would not do this, he would do this instead, and say that the character would do something else entirely, even though I, the writer, totally see it as out of character for them. But I keep being told by writers that my endings to do not work because characters would not fall for tricks or do anything that would lead to their downfalls. It's just not natural that they would make mistakes or give into other characters' far fetched traps, I keep being told. How do I write a story, so that the reader agrees with the writer on how a character behaves, as oppose to a reader deciding for themselves how logical a character would behave exactly? How do I write a character so that he is so smart that he can completely fool all the professionals around him and get away with anything, but at the same time, he can also be baited by the most unlikely of far fetched and illogical schemes? Another weakness of mine, that I have been told is that I rely too much on coincidences to bring plot points together. However, movies do this all time. In Planet of the Apes for example: SPOILER The main character travels into space for thousands of years and then crash lands on the exact same planet on which he came from. What are the odds? Also, only a few days travel from where he crashlands, is Dr. Zaius, the villain. The villain knows the truth about what's going on, that the MC is in search for. What are the odds, that the MC would not only crash land on his home planet after so long, but would also run into the one character who knows all the required secrets, who just happens to be within such close proximity on the entire planet? So how do you write a big coincidence or even more than one, and make it plausible? Thanks for the input. I really appreciate it.
