I have been thinking a lot about how writing groups and articles can say one thing but I often see it done a different way in actual screenplays, even good ones. For example you often see someone telling screenwriter's this for example "You don't tell your audience your story, you SHOW them. You must learn to write a screenplay VISUALLY. Write what they will SEE and what they will HEAR. You might love your characters and know what they are thinking, but the discipline of screenplay writing is how to show it on a screen. When it happens, it may be just done with a look, often improvised on the movie set. So just write the pictures, sounds, and speeches, and leave the rest for the filmmakers." However then you see in taxi Driver this: "He has the smell of sex about him. Sick sex, repressed sex, lonely sex but sex nonetheless. He is a raw male force." So I seem to notice a lessening of rules when it comes to character descriptions allowing it to convey essences. However if I try and do the same in my writing my local group can be harsh and I sometimes think they miss the point, they get so into being technically perfect and not breaking rules but forget the soul.
