A bit derivative and a lame ending, but otherwise pretty good.
19 July 2010 | by (Bradenton, Florida) – See all my reviews

It's a sad testament to the second season of "Space: 1999" that such a flawed episode turns out to be among the better ones that year! While "The Lambda Factor" has problems, it is more watchable than the typical episode on this final year of the show.

The biggest problem is that the show, like many of season two, was a rip-off of a story idea from the original "Star Trek" series. With the addition of Fred Freiberger to the show (himself a veteran of "Star Trek"), many stories would be rip-offs of shows done the previous decade for Trek. The basic idea of "The Lambda Factor" is clearly taken from "Where No Man Has Gone Before"--the second pilot episode of "Star Trek". In both, an outside entity somehow causes certain pre-disposed members of the crew to have heightened psychic powers--powers that ultimately could destroy everyone after one of the crew develops god-like powers.

Another problem with the show is the seriously wimpy ending. Instead of Captain Kirk using a laser to drop a boulder on the god-like transformed crew member, Commander Koenig uses love and an absence of fear and hate to defeat the hostile forces. And then, miraculously, everything goes back to normal and all live happily ever after....whatever.

Fortunately, in between the retread plot and the silly ending, the story is intriguing and worth seeing. Not a great show by any standard, but at least one that is not an so many of the other shows of season two.
