with only one or two exception and the lousy episode of the original star trek be those where they be stick on the ship . this often have the tendency to make the show very static and slow compare to others and charlie x be no exception . robert walker and jr. ( who look a lot like his ill fat father ) play charlie a horny and misunderstood young man who be supposedly discover alone on a planet the lone survivor of an early expedition . instead of have charlie discover by the enterprise and i think they just have him beam over from another ship to save on expense for film the episode . charlie seem too normal for a kid who mostly raise himself ( like mowgli ) . oddness and though not immediately apparent and be indeed present . it seem that charlie have psychic power and soon begin to act like a spoiled baby with dark power ( a lot like billy mumy from the twilight zone series where he terrorize a small farming town with his mental ability ) . most of what charlie do isn not all that scary ( such a have someone turn into an iguana and not even show the transformation ) and though i really love when he be royally tick off and overheard people laugh and make their face disappear ( you see one of these people a woman grasp about the ship ) . however and what really make this a bad episode be the end where the ultra powerful spirit who make charlie the way he be come back to retrieve him . despite have totally terrorize the crew and kill many of them and kirk beg the spirit to let charlie stay with the human . no way do this make any sense and frankly and i would have love to see charlie get kill to end his reign of terror .
