I agree that when I look back on some movies, I get just as excited to see them as I did when I was a child. Others however, have a slightly different feel to them. There are several movies I can watch now and catch onto things I have learned now that I am an adult.
I think it is a good thing for writers to slip adult jokes into movies that children won’t understand. The children get to enjoy the characters while the adults get to feel involved as well. Take Dreamworks Shrek for instance. There is a line in the movie where Shrek looks at lord Farquaad’s Castle and says, “Do you think maybe he is compensating for something?” Children would not understand what the reference really means, but it gives the adults something to chuckle about.
Another innuendo found in a beloved children’s movie is found Toy Story by Pixar. Nothing is actually stated in the film, but one of Sid’s toys is a visual representation of something only adults would understand. One of his toys is a pair of legs from what one can assume is a Barbie with a fishing rod secured to the top of them. If my memory serves me correctly, the toys name is legs. This toy was actually supposed to represent a hooker.
However controversial some of these things may seem to some people, I think they are harmless. I for one never paid attention to the references as a child. Just because these movies are created for kids, doesn't mean people from all ages can’t enjoy them.
