i can see and understand both sides of this argument, but in reality, thats the PG means, its up to the parents to decide if their younglings can see it or not. i went on the 1st day. i loved it (all writing and acting critiques aside) but at first i was thinking that i would not take my 4.5 year old to see it. but kids are so into all toys, games, cartoons, kinds books, etc (just like i was when the 1st one came out 1977) that im starting to thinnk he can prolly see it, but we are having some discussions about what is real and what is fake on tv and movies first for sure. he may wait to see it until the dvd comes out at xmas time, ive found that movie scenes that are intense on the big screen lose some of that on the tv.....
but we'll see. my son and all his other pre-school friend are obsessed with it, and some of his friends have went to see it already and they all loved it even if they did hide their eyes during some parts.....
i know i went at least 6 times to see the 1st star wars in 1977 and i was just turned 7 (which i know is a long stretch from 4.5)
