If you haven't started watching beyond season 2, yet - consider stopping there. Season 3 turns up ghey cowboy action in the neutral zone, a pair of lipstick lesbians and not much plot development beyond Japs beating up everyone looking for more films. Seriously, you could probably watch the final 2 episodes and get the gist with the understanding that you didnt miss much.
I chalk it up to the modern day practice of assigning different actors and screenwriters along the way who screw up the original storyline with political bias, hence fags and lezbos where they don't belong.
As a concept, the storyline is interesting though.
