i watch star trek tos everyday after elementary school in the 1970 and so much so that after a few year i have manage to see every episode but two . those two episode be court martial and the alternative factor both of which rank low in my opinion for entertainment value for trek . i would not see them until i be in my 30 so it possible that not have see them first a a child have make me less open to like the and or it may be that they be just bad episode while for me and i do not think i be reach too far by label them bad . the alternative factor though win the honor a a bottom 5 episode while court martial doesn not reach those absolute low base on some decent acting scene . the reason why i think this episode be so poor be the story be just plain stupid and the character be make to be stupid and especially spock and there be little or no part for character like scottie and sulu and ohura and bone and i mean even yeoman rand would have help and i hat her . lol . ok now it plot hole time and why couldn not they just phaser the time machine so that neither one could get through . just make sure you have the nice lazarus on your dimension and lol . oh well the other lazarus seem like a good guy to go drinking with at a klingon bar and right . anyway and way too much time spend with out guest character and not nearly enough with our enterprise crew mean no matter how good the plot ( which be not here anyway ) it would not get sell . negative even though it trek and it a pain to watch and i would not be next time i see it on . so what be your bottom 3 trek episode . here be mine and i do not think they will change if i re watch them soon and these be base on my memory that go back several year and a a male viewer . the alternative factor and obsession and and be there no truth in beauty .
