NOTE TO SELF: Don't let my 5-year-old watch "Pulp Fiction." Also, don't let him watch the "Star Wars" prequels — not because they are violent, but because they are just AWFUL. But also because they are pointlessly violent. But the awfulness is the bigger factor on that one, honestly. I digress. Here's a reason to be careful about what your kids watch. (I actually use this site all the time.)
This is not to say we should shelter our children from all violence. They are growing up in a real world where real violence happens every day. But there's a difference between cartoon violence and Silence of the Lambs, ya know? You could share this if you are a fan of children not taking out hits on stuffed animals. Your call though.
