Realism, realistic, and Melodrama

A usable definition for the term realism is written in The Creative Spirit as “theater that seeks to give the appearance of everyday life. It is also defined as specific literary style that dominated a large part of American Theater beginning in the twentieth century. On the other hand, realistic refers to an “actual life events.” It gives a more “balanced” view of what actually happens in everyday life events. Melodrama attempts to use the realism style to portray everyday life events, but in a more emotionally driven, exciting way. Two important terms that help describe what Melodrama is are: phenomena and semiosis. Phenomena deals with "making observations and looking at the real and concrete." Semiosis deals with "looking through. It is interpretation of the hyper real or imagined.Melodramas bring what would be everyday situations and turns them into extremely dramatic events, that more often than not, over the top. It uses what is known as polyphany which is the music that helps heighten the emotions of the audience members so that the unrealistic or "melodramatic" scenes can make more sense. It takes the agon or conflict/game and brings it to a climax. One of my favorite examples of melodrama is the film The Princess Bride. Although this film shows the specific nature of everyday life, such as eating and traveling, many of the other events the characters find themselves in are unrealistic and extremely dramatic. There are even points where the film seems to poke fun that it is such an extreme form of melodrama.
My question is whether or not there are many, if any, films or plays that have absolutely no from of melodrama in them. Obviously there are films such as The Princess Bride, which is clearly a comedic melodrama, but are there subtle aspects in almost every existing entertainment pieces?
