i give this movie a single star only because it be impossible to give it less . scientist have develop a formula for replicate any organism . in their lab ( a run down warehouse in l. a . ) and they create a t rex . a group of industrial spy break in to steal the formula and the remainder of the film be one endless foot chase . of course the t rex ( a rubber puppet ) get loose and commences to wipe out the cast . it have the amazing ability to sneak up within 2 or 3 foot of someone without them notice and then promptly bite their head off . one cast member escape in a police car and spend the remainder of the film driving aimlessly through the city . she be of such superior mental ability that she can not even operate the radio . she never make any attempt to drive to a substation or a donut shop and appear hopelessly lose . the t rex wreak havoc throughout the city and there be blaze gun battle and building ( cardboard mock ups ) blow up and but a single police car and or the army and nor anyone else ever show up . such activity must be commonplace in los angeles . we can only hope that a sequel isn not plan .
