"I'm not sure I can take too much of this..."
9 April 2015 | by (Bradenton, Florida) – See all my reviews

The animated "Star Trek" series sucked in many ways. However, often the scripts were decent enough you could almost ignore that the animation was drawn by chimps. Well, in the case of "The Infinite Vulcan" you have the worst of both worlds--terrible animation and an incredibly dopey story--one written by Walter Koenig and Gene Roddenberry!

When I try to explain the plot, bear with me. This is because I really have no idea what I saw and the story is an incomprehensible mess! The crew land on a planet ruled by sentient plants and their leader is a giant clone of a crazy plant-lover from over two centuries ago! His plan was to invade the galaxy and impose peace on everyone. Now, for no real reason, they abduct Spock and try to make a giant Spock to rule over everyone. Huh?!

This is just crap...total crap. I don't know how the voice actors could even utter such dopey lines as you'll hear in this one and my suggestion is that you take heed from the summary--which was spoken by Dr. McCoy during the episode!
