When I was 3, I watched this. This was the first movie I ever watched in my whole entire life, and I loved it so much! It became one of my favorite movies of all time! Although, it does have some intense sequences and a few sexual references, it is not enough to make pre-teens not be able to handle it. Although it is G, I personally would give it to PG. Plus, although characters get vaporized, they all survive. But the movies' message is fantastic and is funny. But for a G movie, it is just too violent.
My MPAA Rating: Rated PG for a few intense sequences of sci-fiction action and violence and a few sexual references. All involving kids.
