My kids are 5 and watch. No one in my family thinks it is a good idea. Luckily I have a boy and girl. The boy already knows no hitting girls, even his sister. There are some fights like a broken leg twisted backwards I would kinda hurry them into another room with me for something i just had to have their help with right away...wink,wink. I don't want them seeing to much blood and guts but i think overall it is okay. They don't love watchin Matt whip some booty quite as much as me but they love cheering him on! The girl isn't into it much but she will once she figures out what HOT means!
