For babies? Defiantly not only babies.
I think they are saying that because it's an animated Disney film, and most animated Disney films are for children, or at least aimed that them. Now, I think The Lion King is different because of it's story/plot. Also, remember that scene with the stampede and Mufasa's death? I'm not sure if all children would find that sweet. Also, the hyenas' revenge on Scar.
I have to agree with Alpha and Suragaha.
Thought the movie(s) may be aimed towards a younger audience, does not make them "for babies".
I know many adults and teens who find it both interesting and intriguing, so don't think that its just for children.
