Cramer gives a spirited performance as the title character. Director Randal Kleiser uses a deft touch with his material. The result is a Navigator that's out-of-this-world fun for adults as well as children.
The brain-assaulting sci-fi second half of Flight of the Navigator is made palpable by Cramer, who deftly conveys anguish during the first half. Now, he wants to go home and his gung-ho attitude makes every dumb effect exciting.
At times a bit too precious, especially inside the young navigator's spacecraft, but the warm regard for character, as well as for our often-inhospitable planetary home, makes for a reasonably good time.
