This is an awesome movie about a grandmother and grandfather turning 17 again(hence the title) after using contaminated soap from their genius grandsons experiment. The story is really good, and the plot is awesome. The characters are played brilliantly by Sister Sister twins Tia and Tamera Mowry, and younger brother Smart Guy Tahj Mowry. It was just an overall awesome movie that never gets boring. I'm trying to find a copy in stores, but it's hard to find! Watch the movie, and you will see what a great one this is!!!!!!! A+++++++
