Rated K for Kid

I think there should be a new movie rating. It is K for kids. These movies would not have that sad part that's in almost all the movies. The sad part is the part where something is sad in the movie. I don't like that part. Other kids that are my age DON'T LIKE IT either. So, if something was rated K, you would know it wouldn't have the sad parts. There should be more movies like that. I liked Hoodwinked because it didn't have the sad part. Whoever made that movie, they should make more movies that are rated K.
