When we are kids, there is mystique about being a grownup. We think that we will be wealthy, carefree and have no one to tell us what to do.
Then we grow up and the fantasy is quickly shattered.
In Big (1988), Josh (David Moscow) is a young boy who is tired of being a kid. He wants to be an adult. Josh makes a wish to grow up at a magical wish machine. He wakes up the next day in the form of Tom Hanks. Josh begins to enjoy the perks of adulthood, but he will also learn about the grey areas and the not so carefree aspects of being an adult.
This movie is a very interesting because it appeals to a wide range of audience members. The adults will remember what is was to be a kid (and sometimes wish they could be a kid again) and the kids might begin to understand that being an adult is not as cracked up as it seems.
I recommend it.
