This was a funny movie! Without spoiling the movie I loved the way they shifted the point of view and switched it around so that the human was the "visitor from out of space". Great idea! Also, loved the obvious "Alien" inclusion into the film from the Sigourney Weaver movie franchise and to make him a pet like our dogs would be, hysterical!
