It's under 17. Sure they can see it with an adult or guardian, but SHOULD they see it? MPAA thinks children under 17 should NOT see that film without adult supervision. Heck, when I was 11 my parents let me watch "Predator" and "Aliens" by msyelf and I turned out fine.
I watched predator when i was 5 and told my great aunts who used to babysit me and my sister. They forced me to watch sesame street from then on lol. I'd like to go see ted.
