But never Lexx. So I was wondering how well it does and how good it’s holding up the test of time.

Late to the party, but if you didn't watch it already, give it a shot. Season 1 (the original movies) is a good introduction. Season 2 is my all-time favorite season mainly because I just love the "planet of the day" genre. A lot of people love season 3 which I personally find pretty uninteresting except the first episode. Season 4 is pure trash gold.
