IS IT SAFE TO LOOK AT THE MOON?

What is melodrama, and why is it bad in a story?

There are questions that bother me. It has to do with writing melodramatic scenes in a story. What is the opinion that is accepted in the writing world? Do readers like to read melodramatic scenes in a story? Do readers think including melodramatic scenes in a story good or bad? If melodramatic scenes are necessary to further emphasize the character of the antagonist/protagonist, should the writer go ahead and include it in?

A story about young people shooting each other; or a story about a student committing suicide because he is bullied at school (or anywhere else he goes, for that matter?); a story about a young person taking revenge on someone who belittled him; or any story about a student shooting his school because his/her teacher gave him/her a bad grade (non-passing grade)?

Let's say the above examples are melodramatic scenes. Are these bad or good in a story? What makes a melodramatic scene good or bad? In what relation?

I think melodrama is good in a story. It not only enhances the story but it also adds a suspense, an anti-climax that would increase the reader's appetite to finish the book.
