Arrested Development and Firefly are probably the top two. I understand why AD had to end, but Firefly could have lasted so much longer and been extremely good. It's terrible to think that a show like Firefly gets cut after barely a season while shows like American Idol are allowed on the air.

I also miss Veronica Mars, though the 'trailer' for a purposed fourth season that was included on the third season DVD wasn't all that interesting and didn't generate a lot of care from me. It was good while it lasted though. The jury is still out, but I might have developed serious feelings for Kristen Bell while watching this show.

Let's see... Buffy the Vampire Slayer and Angel, although the former lasted long enough for a television show and the latter couldn't really go anywhere else. Out of the three Whedon shows listed here, I probably miss Firefly the most. I think the acting, writing, and storyline were far superior than anything on Buffy and Angel.

I also miss Conan.
