According to Variety, Jericho is not being picked up for next season. I know it’s not the best show on TV but it’s definitately not the worst. Still, I would like to know what the hell happens! I want answers! I need closure!
So what shows got cancelled without resolutions? I don’t mean a series ender with an unsatisfying final episode.
Also, aside from fan-fic, is there a way to get answers? Unproduced scripts, writers notes, so on?
Firefly had several questions I wanted answers to:
Who/what is/was Book?
What all can River do (this was partly answered by the movie Serenity).
What was that syringe Inara was going to inject herself with?
Firefly is a good recent example. There were numerous ongoing mysteries and plot threads (Hands of Blue, Shepherd Book’s past, the story behind the Reavers, Blue Sun Corporation, River’s abilities, the various romantic relationships, etc.) that were obviously meant to be examined over the course of multiple seasons. Fan interest in continuing the story was passionate enough to get a movie made, which resolved some threads but left others open. But the movie’s poor performance probably means that we won’t see any more filmed Firefly.
ETA: I just knew that somone would beat me to it. 
Gilmore Girls. Lane Kim in an early episdoe (1st or 2nd one, in fact) says something about her father. She speaks about him in the present tense, implying he’s just out of the house for a bit. But when the show ends seven years later, we never see him or even hear about him again. Where did Mr. Kim go?
John Doe – fun series, audience was growing week to week, cancelled after the first season on a HUGE cliffhanger/question.
No, I’m not still angry about that – why do you ask?
Coronet Blue. This 1967 series was about an amnesiac who woke up not knowing anything about himself, but remembering the phrase “coronet blue.” When the show ended, we still didn’t know who the guy was, or what the hell “coronet blue” meant. Auggh.
Two episodes of American Dad
One in which the Alien “roger” tries to discover his special power
Roger eats a burrito and defecates gold embedded with gems but does realize it
The other where the family goes to live in Saudi Arabia
and Hailey is arrested for being outside with out a male escort.
My So-Called Life was abruptly cancelled in the first season due to low ratings, and basically left the whole show unresolved.
Will Graham and his restaurant partner Hallie have an affair? Will Graham and Patty’s marriage survive?
Will Angela and Rayanne ever repair their friendship?
Now that Angela appears to have discovered Brain’s true feelings about her, what will she do? What will happen between her and Jordan Catalano?
Will we ever meet the mysterious Tino?

Joan of Arcadia. There was this big run-up to what was going to be a struggle between Joan and Satan, but then the series just ended.
Last year’s atypical miniseries Day Break almost ended without resolution when the network pulled the plug about halfway through. But bending to fan demand, the network put all 13 episodes on the web.
Gilligan’s Island: Why was the Professor keeping them there by sabotaging every escape attempt and then making it look like Gilligan was responsible.

The Mystery of “Coronet Blue” Revealed!
“When the Brodkin Organization took over the series, they wanted to turn it into an anthology… so they played down the amnesia aspect until there was nothing about it at all in the show. It was just Frank Converse wandering from one story to the next with no connective format at all. Anyway, the show ended after seventeen weeks and nobody found out what ‘coronet blue’ meant. The actual secret is that Converse was not really an American at all. He was a Russian who had been trained to appear like an American and was sent to the U.S. as a spy. He belonged to a spy unit called ‘Coronet Blue.’ He decided to defect, so the Russians tried to kill him before he can give away the identities of the other Soviet agents. And nobody can really identify him because he doesn’t exist as an American. Coronet Blue was actually an outgrowth of ‘The Traitor’ episode of The Defenders.”
Knights of Prosperity. Will they successfully rob Ray Romano? If not, who is their next target? And how could they expect to take this premise through an entire season? Wouldn’t they either get caught and go to jail or give up trying after one too many unsuccessful attempts?
Invasion, from last year. I liked it, but the series started kind of slowly so didn’t keep up the viewership. It really picked up in the last half of that first and only season. And while some of the plot threads were resolved in the finale, it ended with a big cliffhanger! Ack!
Namely, the pregnant Larkin taking a bullet, and before she can expire, Tom Underlay takes her to the water – where she’ll presumably get taken by the alien critters and go through their duplication process, so that she’ll technically “survive”, like Tom and Mariel
Kidnapped from this recent TV season. Died before it ever had much of a chance, but it was a pretty good show, IMHO. And the shortened 13-episode season/series did resolve the kidnapping intended for that season – but it also left room for possible future plot threads. What’s Knapp’s history with the guy in prison, who escaped at the end? And what ever happened to “The Accountant”?
I was going to mention this one. They left a lot of unanswered questions, and I really miss the show. 
The WB show “Half & Half”, which starred the delectable duo of Rachel True and Essence Atkins, was canceled last year leaving the cliffhanger open about which guy Rachel True’s character Mona would wind up with.
Soap ended with a number of unresolved plot lines, the most memorable of which I guess was Jessica in front of the firing squad.
Dead Like Me.
What was George’s connection with the Gravelings?
But I heard that a direct to DVD movie sequel is in the works for DLM. Maybe it’ll shed some light on that subject.
Well, obviously to have a shot with Ginger.
Or possibly to meet the Globe Trotters.
Yes, but the explanation, such as it is, came thirty frickin’ years after the series ended. I’m still gonna pout over this.
