This is a kid's movie, we adults want it to make sense to us! Of course from the astrophysics point of view this movie doesn't do a good job, but then Star Wars wouldn't make sense either.
Kids enjoy watching this movie and if they are glued to the screen with their mouths half open, then they are enjoying it.
Spark: A Space Tail has humor and action.
Adults, stop giving this movie a low point only because it doesn't entertain you.
