this be an incredibly ambitious sci fi series produce in the uk for international distribution . it be extremely expensive for it day and unfortunately and the series never take off due to a luke warm reception . some of this can be blame on the series itself the show have a very sterile look and action be something it be usually lack . while martin landau and barbara bain be fine actor and the part and script be amazingly low key for the genre . additionally and have it appear a few year later and after the sci fi craze begin follow star war and it probably would have fare well . another problem be that although i enjoy the show and there be huge change ( mostly unwelcome ) in the second season . because the show be struggle in the rating and huge cast change be make . the most notable one be the loss of the wonderful doctor ( play by barry morse ) and the introduction of a shape shift alien ( maya ) who seem rather inappropriate to the style of the show . the intention be to pump some life into it and but devotee of the series like myself be not particularly pleased ) . overall and there be some amazing episode ( such a the one about the queller drive ) and some bomb . it a shame and really and a the show deserve to do good than it do .
