A good friend of mine took my almost 8yo daughter and three of her friends saw the Incredibles last weekend. For her, and all of them apparently, it was not too intense... my friend said he was going to see it a second time, he liked it so much.
..but we were sitting next to 5,6 year olds, it looked like....
..and it's not a sweet Bug's Life or Monsters,Inc.
IMO.
