But, they went through the wormhole at the end of "Wild Green Yonder" and they're fugitives! They could be thrown out into who-knows-where in time and space! I thought that was a great ending to the series, and I don't know if they can top it. "Wild Green Yonder" was a great movie, but the other DVD movies were just awful and didn't quite hit their stride. I think they should quit while they're ahead.
