I am NOT a sci-fi, futuristic and/or 3-D movie goer. However, this was an excellent movie and I recommend it to young and old alike. I believe grandparents will enjoy this movie as much (if not even more) than their kids and grandkids. Be sure the theater you choose has 3-D capabilities; I saw it at an IMAX in 3-D. Solid plot has you pulling for the underdog.
