The pilot episode written by Gene Roddenberry is excellent, but the show goes nowhere, all hugger mugger and no real story. Roddenberry's basic idea, that contact between humans and superior aliens will not be all black and white but will be filled with ambiguities, is a good one. Later writers, however, think in terms of good aliens and bad aliens. The use of female actors to play androgynous aliens was a good idea, but in later seasons everybody except Da'an overdoes it. In the third season, there are a number of scripts by Howard Cheykin, who is an excellent writer, and who wrote some memorable episodes of The Flash TV series, as well as some great graphic novels. However, he is unable to do anything here, because he is locked in to what is really not a workable story line. I have not watched the fifth season, but I have read that it throws out most of what was established in the first four. For scifi completists only.
