The theme in every story is important because it tells us what the character learn during his/her adventures.I think understanding a theme of every story is important because you learn something about every book you read it can also connect to your life.
Themes can be found mostly every where.I watch movies and movies have a theme in the story.I had read the book name Warcraft sunwell trilogy and theme of that book is that your gonna need friends to overcome difficult problems. This theme is meaningful to me because it is true you do need friends to help you overcome difficult problems.
