I won't go into detail with spoilers, BUT abrupt cancellation of this series that has a rabid cult following left the plot hanging at the most unspeakably bad critical point I could possibly imagine!
Similar situations with the wonderful but woefully short lived Firefly and the earlier but much longer running and similarly popular Farscape led to fan outcries and wrap up movies, though I'm not sure this cliffhanger could have been resolved in less than a season short of actual unabashed divine intervention...
Premature cancellations seem to have become a far too common occurrence - one almost wonders how the redoubtable Babylon 5 was allowed to finish gracefully, though its sequel series did not fare so well
