One of the best science fiction TV series of all time has to be Star Trek: The Next Generation (TNG). It is far beyond the original in its believe-ability and I think its more entertaining than Deep Space Nine or Voyager (although Voyager seems pretty good). Now I`m not a Trekky by any means, but what really convinced me was the science of Star Trek. Everything in the series is believable science, even if we can`t do it today. Faster than light speed, fusion reactors, even teleportation, are all theoretically possible. I think that`s a main reason that I enjoyed the series so much. It wasn`t crazy stuff that could never happen. more info >>
