wow interesting.. well, you re the parents u always can teach kids what's wrong or right, if u see anything sucipious from kids watch movie that affect behavior, all you ahve to approach to them its's wrong. But i don't think that movies would affects unless they re brainwashed. I'm believe parents should be there for the kids from wrong to right.
Matter of fact, i would like watch Chicken Little, if i see anything bad. I wouldn't let kids see it. So, don't let it stop you. Alike, i don't like power ranger myself, kids re too way voilents after watch them. So, its depends on the actions/adventures.
