I know the show is old, but I shame myself by not giving it attention earlier. I somehow get the same feeling that I got when Fringe finished: I want more, but I don't want it to spoil with overcomplicated plots and lifeless seasons.
For the 3 seasons this show got, it was seriously well made, with a lot of attention to details. I know the special effects lacked in ...well, everything, but that didn't break the narrative one bit.
Languages and dialects for all the alien races, specific music, well developed characters who blur the lines between good and bad, nice twists here and there, great dialogue, compelling storyline. I was amazed on how much love was put in this particular show.
For everybody saying it's underrated, believe them. It truly is a show that could've gone further with ease, but at the same time, it's good it didn't get to spoil at some point.
Watch it, love it, miss it afterwards.
