Hmm, I don't have a good answer for this actually. I can't think of any cancelled movie or TV show I was hyped for. I've heard of plenty, but most of them were video game adaptations and it was probably for the best that those were strangled in the womb. x) Like the Shadow of the Colossus movie. It could have been surprisingly good, who knows, but I just don't feel like the kind of game SotC is lends itself well to a film. There's more dialogue in this fuckin' thread than in the whole game!
It's not quite in the same wheelhouse, but Firefly is one of the only close answers I can think of. I got into the show a couple years after Serenity was released. I loved the show, was supremely disappointed that it was a one season show that was cancelled instead of being made to be only one season. Serenity helped lessen the blow, but it still sucks hard. Police Squad! gave me similar feelings. Fucking brilliant show. It was only one short season, but at least it didn't have an overarching plot that was left hanging. It came back as The Naked Gun films, which were quality entertainment. Of course they are rebooting that series now. I do my best to be at least a little open minded with reboots, but I don't have a good feeling with this one. Hopefully I'm wrong.
