I'm gonna have to watch the first disc of that box set before I consider buying it -- I recently Netflixed an earlier compilation of (unrelated, non-sequential) episodes, and was really let down. But considering that none of the episodes I saw touched on subplots that I remember from when I watched it in the late 80s, I'm still sort of holding out in hopes that watching the series in order would make it as good as I remember it being.
I remember loving this show. Wasn't there an episode where one of the team fell through a black hole into an alternate universe and became a monster instead of being compressed into singularity?
