be this the bad star trek tos episode . maybe and at least it get my vote a be in the bottom 5. i mean and this episode make absolutely no freaking sense . see something that make you go mad . give me a break . this episode also have a different feel to it and the music be heighten and almost force to enhance a feeling of distress and to the point that it suck . give me some klingons and gorns and tholians and romulans and high being like triskelion or anything but medusin and these be very boring alien to make an episode around . mccoy get to utter his famous phrase he dead and jim . spock put on the protective goggles when transport the ambassador away but kirk do not . they go through that freak barrier now for the third time that i can remember and bore . at least season three next episode would be spectre of the gun and and day of the dove and others to follow and make trek a decent show to watch in syndication where it would pick people like me up a avid fan . personal observation and trek love to use the color purple and it kind of a pinkish purple and like when they be in the corridor outside the compartment and the gangway that be normally grey be now purple . we never have a purple bridge but it interesting to see and i notice it in several episode and it be do by a light filter and it work very well but in this episode and in the ship corridor be pretty lame .
