I have always been led to believe that when writing a novel, the content has to be believable. ie; if you are hanging from a cliff, an areoplane could not hover close to you so you could jump on.
Now, I have just watched the latest bruce Willis film and up until a certain point, the storyline was great. Then they have to throw in the completly un believeable scenes that totally destroy the film. Only in Hollywood as they say!
Umm...I don't believe the latest Bruce Willis film is based on a novel, and even if it was, lots of screenwriters don't play by the same rules as novelists. Mainly, they don't have as much respect for their audience's intelligence. I was invited to co-write a screenplay from an unpublished novel of mine, and it was an unforgettable experience, no matter how hard I tried.
The person who invited me is a small-time writer/director who's claim to fame was a thriller screenplay he wrote many years ago. I saw the movie made from it, and read two more of his screenplays, and what stood out the most to me was his use of "easy outs," which is to say, narrative techniques without any thought behind them.
For example, his work almost always has a moment where the MC discovers a horrible killing, notifies the police, and is immediately arrested for the crime, without a trace of evidence suggesting he did it. I recognize it as a standard plot device -- hero is wrongly accused of crime -- but this guy never bothers to figure out a reasonable cause for the hero to be arrested, and it never rings true, and in fact, comes off as stupid.
He also thinks nothing of giving his villains supernatural abilities, like the ability to simply appear in a victim's car or home, without any explanation of how he even knows where the victim lives, let alone how he got into her house or car.
It's the kind of lazy, self-indulgent writing I hate, and I can't imagine how anyone can do it unless they think the movie-going audience has a collective IQ of 50.
The reason this kind of crap goes on is that Hollywood is run by hucksters who know how to sweet-talk investors and blow smoke up people's asses, but know nothing about writing or storytelling. Same's true (perhaps even more so) of TV.
When David Chase first pitched the Sopranos to Fox, the executives (1) wanted to know, "Does Tony have to see a psychiatrist?" and (2) wanted the cast to consist entirely of beautiful people. Thank gawd for HBO...
Actually, a season or two into the Sopranos, Fox put on its own Mafia show, I think it was called The Family or some such. All the actors were movie-star beautiful. The show lasted about a half-season.
At least book publishers still leave the editorial decisions to editors...
