I enjoy both
these shows. They play side by side on the MeTV Network. I've noticed though, that beside maybe the whole quality of special effects thing, I don't see a whole lot of differences in the 2 shows.
They both utilized the earthly similarities on alien planets. Just like Lost In Space
, the Star Trek
producers found excuses for the crew to end up in Nazi Germany, Ancient Rome, confronting a Greek God, a shoot out at the OK Corral, etc*.
Which one wins out? That's a tough one. I got to say though, at least Lost In Space had Dr. Zachary Smith.
* Fortunately, and I think this is mainly due to the timing of the original series, there was no exorcism scene like there was in The Next Generation
