Gonna stand up for this movie. All the parents saying theirs too much violence and stuff. PG rated shows/movies are ment to be watched by 8 year olds or older with parental guidance. Of course your 6 year old would be disturbed or freaked out. It's a great movie with great humor and amazing plot. Voice acting, animation, you name it! I reccomend watching this with your family. If you are a parent or guardian who doesn't like movies with violence this isn't for you. This movie talks about subjects like death and to put it bluntly alcohol but in a "cat friendly way" also known as milk. Anyway pretty great movie if your fine with your kids seeing this stuff.
The story is brought very wonderfully and the plot is very interesting and grabs your attention fast. I think it's a great movie to watch with your family.
