Having just moved I had to set up my DVR again to record all my series. I was going through my notes of shows I tape and found a few have been canceled that I'm kind of bummed about.

Rookie Blue - Show was getting a little old, but Missy was pretty damn hot to look at.

Graceland Only lasted 3 seasons, was getting tired of the main character but over all wasn't a bad show.

Dig Only last 1 season, starred Jason Isaacs and Anne Heche. Thought this was pretty good, surprised it was 1 and done.

also hearing rumors Castle might not be lasting much longer.

my DVR list is surely getting smaller.

Hasn't Castle been on the air for like 7 or 8 seasons now? Either way that's a damn good run and IMHO it's best for a show to end gracefully and on a high note than for it to overstay its welcome creatively speaking.


As for cancelled tv shows that I really liked these are the first 5 that came to my mind,

Caprica - lasted 1 season
Rome - lasted 2 seasons
Firefly - cancelled after 14 episodes produced.
Space Above & Beyond - lasted 1 season
Crusade (spinoff of Babylon 5) - 13 episodes produced and was cancelled by TNT before the first episode even aired.

Vegas Dennis Quaid and Micheal Chiklis squared off for control of 1960s Vegas.

Firefly
Space Above & Beyond
Enterprise
Stargate SG-1
Stargate Atlantis
Stargate Universe
Jericho

Well, technically every show that is no longer on has been cancelled by someone or other, unless we're specifically talking about prematurely cancelled series. I won't repeat any listed here already. This is just a tiny part of my list.

Farscape
Prey (I don't know if anyone remembers this Debra Messing series)
Invisible Man
7 Days
First Wave
The Clone Wars
Sledge Hammer
Stargate SG-1
Stargate Atlantis
Stargate Universe (all 3 series were cancelled before they were ready to stop)


And of course:

Star Trek





The Jedi Master

Enterprise
Crusade
Alphas
Jericho
Terra Nova

There are more, I just can't think of them right now. Seems like every time I start enjoying a new series, it gets cancelled.

*Edit: While I was posting, so was Jedi. 7 Days was an excellent series with a great premise, as was Sliders. Both could have run practically forever with some decent writers. While Sliders had a good run, I think it could have run longer with some new writers. They seemed to run out of ideas the last season. And 7 Days hardly even got going before it was cancelled.

Forever with Ioan Gruffudd http://www.imdb.com/title/tt3487382/
Was quite enjoying this show, and I quite like Ioan as an actor, especially in Hornblower.

One Punch Man Found out that season two was announced two days ago
Green Lantern: The Animated Series
Rocko's Modern Life

Just some context because that's a child's list. I got pissed off with life so much that I prefer to watch cartoons, and animes. Like One Punch Man, I enjoy shows that don't take themselves seriously. Any movie with serious politics, intrigue, gossip, or manipulation, I prefer not to watch cause 100% of the time I will/have experience/d it in real life.

+1

The Unit
JAG
Brimstone
Alien Nation
Supercarrier (haha just kidding, but it was funny to watch)

v6,
boNes

Too many to name. Just know that if I like a show it's the kiss of death.

oh I liked the Unit as well. Southland was another show that ended before it's time I thought.

Flintstones
Bugs Bunny
Catdog
Pinky and the Brain
Pink Panther

This one! Even though the series was cut short, they concluded it with "Farscape: The Peacekeeper Wars". The dreaded wormhole weapon was one of the coolest things I saw on TV or Theaters.

"Pretty please, with cherry on top..."
"Happy Birthday Scorpius"

Edit:
Just recalled another series I liked which was cancelled abruptly. One cast member left and the ratings just dropped.
Coupling (original U.K. version)

I would like to include The Muppet Show but after some search it seems like Jim Henson intentionally wanted the show to end before it lost its appeal.

I was always touched by this print.

Space Above and Beyond
Sarah Connor Chronicles
Dollhouse
Tru Calling
Southland
Harsh Realm
Keen Eddie (TV series with a young Sienna Miller - cancelled by who else? FOX! Those Bastards!!)
Fastlane
Mickey Spillane's Mike Hammer (Before Keach got busted for coke possession. The show was not the same afterward.)
Friends With Better Lives
The Unit
Cold Case

Firefly, just loved it.

Strange Luck was a really neat show (also aired and killed by Fox) where DB Sweeney was a photographer with, well, strange luck. If it was improbable, it would happen to him.

Apart from always being where there was a bank robbery or something bad, he also routinely paid for lunch by buying a scratch ticket. Of course it would be a winning ticket - though only enough to pay for the meal and a little bit more.
