confused.

So whilst watching the news this morning, a commercial break aired a McDonald's commercial, highlighting the Avatar happy meals. Here is where my confusion begins. Isn't Avatar a PG-13 movie? Granted its a cartoon, action, love story all wrapped up in one... why the crap would McDonald's have a happy meal with an Avatar theme? How many 13-year olds do YOU know that buy happy meals? Badly done McD's... badly done.
