Which Spin-Off would you prefer?
Combine the first three(no more Kai). I think it would be funny to see Stan and Xev trying to avoid the other ship, then keep running into them. Hijinks ensue for about 23 episodes, then Priest gets mad when Stan hits on one of his hot chicks. They start a fight and Stan gets kicked off the Noah. So start the Insect Wars as fought by two complete dumbasses. How’s that for a prequel?
Having the seriousness of Kai’s situation contrast with the ineptness of the rest of the crew I think was detrimental. Don’t get me wrong, I love the show. I just think blending the two was a mistake. Kai to me was like a big brother watching over a birthday party. You can’t really just have fun.
With Kai really dead the door is open to market the show with a distinct trait other than “want some strange?”
