Every cancellation? Don't be silly. People only celebrate the cancellations of shows they don't like. Let me explain to you how it works. A few years ago, CBS had this show called Close to Home. CBS cancelled it after it's second season and replaced it with Moonlight. Close to Home fans of course, were incredibly pissed off that CBS cancelled their show so they rooted for Moonlight to fail and were overjoyed when it got cancelled. Of course, CBS replaced Moonlight with the Ex List and Moonlight fans were pissed off that CBS cancelled their show and they actively rooted for The Ex List to fail. They were of course overjoyed when The Ex List was quickly cancelled. Now, the next question I'm sure you might ask is "What about fans of The Ex List? Weren't they pissed off at that show's cancellation and did they root for it's replacement, Flashpoint, to fail?" And the answer, of course, is no, because there are no fans of The Ex List.
No, they don't. CBS didn't air all of the episodes of The Ex List. ABC also didn't air all of the episodes of Pushing Daisies or Eli Stone. Speaking of Eli Stone, that's another reason to root for a show to fail: annoying fans. Seriously, if you ever critiqued Eli Stone where other Eli Stones are around, they would flame you to no end for dare decrying what they consider a masterpiece. When news hit that Eli Stone got cancelled, I was overjoyed. It was a real screw you to all those annoying fans.
Wait a minute, you were complaining about Fox cancelling a show when you didn't even see the show?
