This movie brings the story full circle. If you haven't seen the first two, your missing a lot of the background.
Overall I loved it, it was entertaining and showed some of lifes complexity and how kids grow up. This movie teaches a good lesson in sharing, being nice to your toys and how to pass them down to others.
I def would recommend it to others, even I enjoyed seeing my one of my fav movies from the the 90's come to a good conclusion.
