Firefly of course was the greatest tradgedy in the history of cancelled television, and for that, Fox must burn.
As for the live-action Tick, meh, it was pretty terrible honestly, a good idea poorly executed. Now, if we were talking about the animated series, there was a show with some traction and a good grasp on the bizarre sort of humor that is "The Tick".
I'd submit one possible addtion to the list: "Drive". They aired four episodes in the space of eight days (EIGHT DAYS!) and killed it before they could have realistically had any idea what audiences thought about it. Fox's excuse? It was dropping their viewer numbers for the show in the following tiem slot, "24". Nevermind that the particular episode of 24 that had the drop in viewership was up against the season premiere of "Dancing With the Stars," a show which (for no reason I can fathom) at the time had viewership second only to "American Idol". Don't even consider the possibility that "24" was getting a bit tired by this point. When you introduce a show with the cast breadth and character depth of "Lost," it's going to take more than a week for people to get into it, but it's the type of show that builds a large following through word of mouth as it goes on. It just takes more time than a whopping eight days.
Anyway, I'm done ranting, return to your regularly scheduled forum browsing.
