You sure are a victim of your television.
You really think little kids are even going to be interested in this? This is going to be something adults want to watch, if the adults are watching, the adults will see the warning screen. If it's just kids, they'll flip past it looking for a cartoon, lingering no longer than they would a documentary on the great accounting firms of the 20th century.
Thank you. I was having quite a bit of trouble imagining my four-year-old niece pestering my sister to let her watch.
(Now, her two-year-old twins are a different story . . .)
