Too soon: Counterpart. A truly marvelous science fiction thriller that explored the concept of a parallel universe and starred J. K. Simmons. I'm still fuming that Starz cancelled it after two seasons. It's not even available to stream anymore...

How to with John Wilson. Not too soon for the usual reasons. I believe he decided he had said his piece. But god damn do I want so much more.

Too soon: The Critic. We deserved more than 23 episodes of this brilliant show. It's too bad that the first season was on ABC who didn't know what to do with it, as they put it on before Home Improvement which was a completely different concept.

Too late: King of the Hill. It should've ended when Luanne and Lucky got married like it supposed to. Few of the episodes after that were memorable, and the finale wasn't as good as it could've been.

Both: Family Guy. The pre cancellation seasons were funny and the first couple of seasons after the revival were as well, but it insisted upon itself after awhile and the characters became more mean spirited than they originally were.

It's a Canadian show and I have no idea how it lasted for more than one season.

Even though I'm a fan of both shows 9-1-1 and 9-1-1: Lone Star have both been going on for far too long, them being forced to keep the teams together and not have any major character deaths, job changes, or major new additions really hampers how much they can do with the characters.

Terra Nova, Whiskey Cavalier, The Premise, and Y: The Last Man all ended too soon as well.

Chop Sockey Chooks.

Ended too soon.

Utopia : John Cusack repeating "what have you done today to earn your place in this world"? still gives me chills. Deserved to be continued. Then I watched the UK version, equally good and aborted too
