Here's the first season:

Be warned, it's very rough around the edges, occasionally soft-core, often outright insane, but also occasionally brilliant. For example, people often credit Buffy for pioneering the musical tv episode, but Lexx did it before. Brigadoom, season 2.

Because it was a crappy show, it gave the writers more freedom to go nuts.

Season 3 gets very philosophical and is often a slog. I gave up on season 4.

If you want another cult show, but with far better production values, check out Farscape. If you've ever watched Stargate, you'll recognize a few of the actors.
