***(3) out of 5 stars
A cute tale about a mean big brother who thinks his annoying little sister is an alien. Well... turns out he's sort of right! She's actually a gateway between dimensions, allowing aliens to enter our realm by, basically, being blarfed out of her mouth, tiny little space-ships and all. Big brother's dreams of saving the planet or gaining world dominion are dashed, however, when the aliens in question turn out to be missionaries, wanting only to spread the word to the world about smiles and happy feelings. Needless to say, big brother does some more rude things to his precious little baby sister, but sibling love does come through in the end.
