What TV show got canceled on a massive cliffhanger that still frustrates you to this day?

A.L.F.

Heroes. Super perfect with the motto "Save the cheerleader, Save the World"on the first season. Then, second season's quality went downhill and they had more seasons from there but they were garbage.If not for those problems, Heroes would certainly be the Top 1 super heroes series up to this day.

Jericho, sort of. It didn't really end in a cliffhanger, but I'm still not sure the alternative was any better. The first season introduced multiple intriguing intertwining plot lines. Then instead of cancelling it immediately, the show was given a shortened second season to wrap things up. Most open ends were closed in that, but in a very rushed and simple way. It missed a lot of opportunities to expand on those plot lines before closing them in a much more satisfying way.

And as a bonus answer, not a TV show but the Divergent movie series. When reading the books I was devastated by the ending and wondered how I didn't remember that from the movies. Then someone told me the movie series split the last book in two parts, but the second part got cancelled and thus the movie series ended halfway the conclusion of the series.
