Shocked by the poor reception here
Just watched it with my wife and kids and am shocked by the rough treatment here.
Does the movie have any scientific accuracy? No. None at all. I am always shocked that people feel the need to criticize movies, especially kids movies, for things like this. This is not a scientific movie. No one, not even a kid, is taking any scientific knowledge out of this film. Another poster somewhere complained that because of this movie kids think other stars are billions, instead of trillions, of miles away. For real? The kids that this movie is aimed at may not know what a billion is, probably don't know what a trillion is, and definitely don't understand powers of ten enough to understand how vast the difference between the two are. They are not remembering this fact, much less "learning" from it. An 8 year old hears "the planet was far away" and moves on.
But the fun factor is there. The inside jokes (the dog looks like the creature from 'Alien') are great. The more obvious humor will keep the kids laughing, and often the adults too. This is just a good time movie. It's simple. It's not deep. But it's fun and richly entertaining. It's not Pixar, but its much better than the run of the mill kids fare.
