Besides DS9, which of all of the Trek incarnations was the most plot driven, The Night Stalker, the show that Chris Carter has openly acknowledged as being the inspiration for The X-Files, did not make the list either. The Night Stalker was absolutely one of the finest show's of the 70's and is in the midst of being brought back for the 2005-2006 TV season.
It was good to see often missed shows make the list, like one of my childhood favorites The Wild Wild West, but at the same including stuff like Andromeda and Earth - Final Conflict over other shows seems to be a mistake.
