Imagine you and your friends decide to have a contest to see who can draw the best picture. You all have different styles and ideas about what makes a good drawing. One friend likes to draw funny cartoons, another likes to draw animals, and another likes to draw people.
The Golden Globe Awards is a bit like this contest, but for movies instead of drawings. Each year, a group of people called the Hollywood Foreign Press Association watch lots of movies and decide which ones they think are the best in different categories, like Best Drama or Best Musical/Comedy.
Now, what's a musical or comedy, you ask? A musical is a kind of movie where the characters sing and dance to tell the story. Remember when you watched "Frozen" and Elsa sang "Let It Go"? That's an example of a musical. A comedy is a movie that tries to make you laugh. When you watch a funny movie like "Finding Nemo," that's a comedy.
So, if a movie is both a musical and a comedy, it can be nominated for Best Motion Picture – Musical or Comedy. This means the movie was so good that the people in the Hollywood Foreign Press Association thought that it was the best movie that was both funny and had lots of singing and dancing.
The movie that wins the Golden Globe Award for the Best Motion Picture – Musical or Comedy is like the friend at your drawing contest who had the best idea and drew the best picture. It means that lots of people liked the movie and it will become very famous, just like how the best drawing from your contest might get hung up on the fridge for everyone to see.
