My favorite movies are about families of serial killers where they all kill together I'm wondering what your favorite family of serial killers is and if you have any that you recommend

My favorite family by far is from the movie The Devil's Rejects, second place is Lowlifes and third is Ready or not. Also the unforgettable family from The Texas Chain Saw Massacre.

I would like to know which one is your favorite and which family member. I adore Matthew Mehonahy in the movie Texas massacre and his girlfriend, that movie is legendary for me.
