Yeah, I think the story just plain didn't really have enough of a chance to go anywhere; no real ability to make a third entry in the series, really. The first two just didn't take off. Which is a shame, I think they should have. So the story that is there is kinda unfinished. I always figured it was meant to extend beyond that.
Or at least that's the impression I get. Chris can always feel free to point out how amazingly wrong I am if I've gotten that all incorrect.
