The most wonderful part of the movies are their diversity. There's a genre for every emotion you could be feeling and you can choose which one its best for the moment. Also, I like drama movies a lot thanks to their amazing messages and how sometimes they shape our way of thinking. They offer you views of life that you could not have experienced any other way.
I must disagree with the "movies better than books" part because reading a book gives you so much freedom to interpret and portrait the elements of the story. However, I believe they are a good complement. Movies sometimes shows us things we could not have imagined and the best part, the soundtrack. It sets the mood splendidly and adds a richer layer to the whole experience.
And about horror movies...I also don't think they contribute too much but I'm a bit of a coward too, so maybe it could be that hahah
