It might be a little intense for someone that young, but... nothing really objectionable. I think it's really intended for a slightly older audience, but if she doesn't get freaked out easily it should be ok.
"but if she doesn't get freaked out easily it should be ok."
She LOVES...loveslovesloves...the charge of the Rohirrim in ROTK. She thinks its hysterical when the Orcs freak out and run away under the charge of heavy horse.
"Dad...look...the monsters are scared! Bunch of fraidy-cats! HAHAHAHAHAHAHAHAHAHAHAHA! Go horsies GO!!!"
I just may take her to see it next weekend then - thank you for the info.
