Radio drama's best action is in the relationship of characters.Love, hate, passion, all that stuff goes really well in audio onlyas expressed in voices, dialogue and narration if needed. Even themost passionate scenes expressed in groans and sighs are reallyexcellent because they leave a lot to the imagination and increaselistener involvement. Just don't try to do a Fencing duel in aradio show. Any play-by-play would have to be in French to describeit and the attendant grunts and groans of the participants don'tclue in the listener very well.Conversely, television and visual storytelling thrives onfights, chases, all kinds of tussles. The best TV and filmstimulates the eye with intriguing angles and colors, characterswhose faces the camera loves and fast paced, breath-taking action.But perversely, watcher involvement can be shallow as the imagesbecome eye candy and easily forgotten. Even more perversely musicand sound effects, the audio presence of visual storytelling iscrucial to clueing the viewer into the correct emotion. Just watchsome TV movies with the sound down to test this well-knowneffect.Radio drama presents an audio outline of the story which thelistener willingly fills in with their own internal impressions (inall senses.) The best visual drama also uses the imagination tostimulate the viewer. Most film is biased toward the eyesight'sfickle preference for fast-moving bright pictures along withsupportive audio to move the story along at the cinematographer'sand editor's choices, not the viewers.
