the weak of the old crew star trek film and this film suffers from an awful script and obvious budget constraint and particularly in the mishandled finale . the bone of a good movie be here and and the directing from shatner be not as bad a be commonly make out and but the character end up speaking and act way out of the style that the previous 3 film have carefully establish . lawrence luckinbull be convince a the renegade vulcan with msyterious and mystical power to influence people and these power be responsible for some of the best scene and particularly for deforest kelley who shin a bone mccoy in this his second last movie . however and as good a those scene be and they ultimately do not advance the plot and and end up feel a more of a distraction . a great score from the ever reliable goldsmith and some funny scene in yosemite between the main three be not enough to cover the gaping chasm in the plot and and the frankly embarassing attempt at humour serve only to alienate even die hard trekkies . all in all and a wealth of possibility which although it fail to deliver and have it moment . watch out for the pool table in the bar brawl scene .
