Once again we visit two tried and true plot devices: Stranger in a Strange Land and The Hero's Journey. This colorful and humorous outing is directed by Tim Johnson ("Sinbad: Legend of the Seven Seas") with a screenplay written by Tom Astle and Matt Ember ("Epic") based on the novel by Adam Rex.
This animated PG movie from DreamWorks is entertaining; even the title sequence has a good laugh. Of course the adults find this story more predictable than the children; on the other hand adults are amused by many, many bits that go right over the youngsters' heads (e.g., a reference to metric tools).
The voices provided by Jim Parsons ("The Big Bang Theory") as the alien Oh and Rihanna ("Annie" - 2014) as earthling Tip are outstanding and mesh perfectly with the excellent animation that conveys their emotions to a "T." They get able assistance from Steve Martin ("The Big Year") and Jennifer Lopez ("Ice Age"), as voices for the self-centered Captain Smek and Tip's sweet mother Lucy, respectively.
