What are your favorite canceled TV Shows?

We all have plenty of shows we enjoy throughout the years, but not all of them survive their entire intended run, be it because of ratings or whatever else. So what are your favorite shows that you liked but it got canceled? How long did it run for? And if you know why it was canceled, feel free to provide that too.

Teen Titans - some bullshit.

Hannibal
Scream Queens
Victorious (idk if cancelled but I need more of this)

Knight Rider 2008. It was fun for me but the show only had 1 season :/

1. Hannibal: Need I say more?

2. Babylon 5: Crusade: A sci-fi series about an advanced warship pressed into service to find a cure for an alien bio-weapon that'll wipe out all of humanity within a couple of years. It ended on a major cliffhanger kind of like what happened on the ending of Hannibal. It lasted a season and was canceled due to TNT's late 90's BS.

3. Airwolf: I watched the hell out of this show when I was a kid and it had a killer premise as well. It technically had four seasons with three on CBS before it was canceled and then picked back up for a fourth season with a slightly different cast on the USA Network before it was canceled again.
