Dead Like Me - Awesome dark comedy. You could really connect with the characters too.
Star Trek Enterprise - Okay, I know this wasn't the best Star Trek, but it was still good. The "Temporal Cold War" was a continuity nightmare, but it was an interesting premise. I am glad they gave it some closure, but a season or two more would have been nice.
Crusade & The Legends of the Rangers - Babylon 5 was an excellant TV show, and it's spin-offs were also good. Crusade was good, yet it only lasted a season and it had no closure. The Rangers pilot was also interesting, and it's a shame it was never expanded upon.
