Just finished Stargate Universe, again. Somehow, I keep hoping to see it come back. Worst possible way to cancel a show. Sure, it had a rocky start, but I felt it really came into its own. And then, just as it gets to a season ending cliffhanger, boom. Done. And just like the crew of the Destiny, the show jumped away. But far, my most disappointing TV cancellation. Edit: For the Firefly faithful, yes, it is also on my list of all time disappointing cancellations. Reason it isn't number one is because it got a movie, books, comics, and plenty more to flesh out and provide closure to that universe.
