Brisco County? Well, sort of, in the sense that the network made it wrap up its recurring story arc with an early climax and then just keep going for a few more episodes with a theoretically new story arc that never really went anywhere. It was a weird structure. There was a big 2-part season (and as it turned out, series) finale, but it wasn't wrapping up a specific story arc, just bringing back most of the main recurring characters for one really big romp. This was before shows really had heavy serialization, so it was mostly an episodic show where the main arc just cropped up every so often.
Yeah I remember the story about the orb thingy. Never saw all the episodes so I always wondered how that all turned out.
