the story be similar to et represent an extraterrestrial run around on earth and try to come back home . while it stay on our planet and it will create friendly tie with human . but and unlike et which exude drama and comedy and poetry and this movie be only fun . it be indeed a pure dysney production represent it core audience be child and the movie be more more in the visual than in the message . thus and you will find some funny scene ( the first sighting of the town and a cosmic stray toaster ) and the casting be experiment and with special mention to doc and who rejuvenate in a mac fly character and and to hurley and who seem open to auto derision . ice on the cake represent the main title be score by danny elfman and and like every other great composer and you recognize his voice before he be even credit .
