This film is populated by stock characters. The hero, a senior teen, wants to get away from the trailer park where he lives with his mother and is the de facto handyman. His girlfriend is a sweet person whose chief concern besides the the hero is her "granny". The hero's little brother about age eleven has a collection of Playboy magazines and is kept in line by the threat of disclosure. The chief nasty, who chews the scenery, has joined forces with a powerful alien race which wants to conquer the chief nasty's confederation of planets where the scenery-chewer wishes to rule.
What brings the two sides together is an arcade starfighter game which the hero learns to use so well he breaks the record. On the heels of that success comes an alien, a galactic headhunter, drawn there by the hero's success. Eventually , the hero trained by the arcade game as a gunner is teamed with a reptilian mercinary pilot, to whom the hero refer as a "gung ho iguana". Through circumstances, the pair become all that is left of the defence force.
What separates this plot and its characters from a rejected Star Trek episode is Centauri, the headhunter, played with great gusto by Robert Preston in his best Prof. Harold Hill voice and manner from The Music Man. He lights up the sky and the film.
The special effects are primitive but adequate; the aliens interesting enough. For all its limitations, the film is a pleasant enough evening's entertainment.
