It was no secret that Bleach was losing its time slot to Rock Lee, but the complete cancellation of the series is quite shocking. Bleach has been slowly declining in popularity, and apparently has been eclipsed in rankings by the newer shonen series Toriko, but this cancellation makes me wonder if it was doing worse than I had originally imagined. After all, the manga itself was set to enter final story arc soon, so the anime adaptation would not have been too far behind.
The idea that Bleach may never receive a properly animated ending is frustrating as a fan, but there is a bit of hope. For a series as massive as Bleach, it's entirely possible that we may see the resurrection of the series with the cancellation of the manga.
So hit your messaging boards and anime groups, and get ready for some bitching. If you thought that fanboys were vocal about the filler beforehand, just wait until they learn they can blame the demise of the series on it.
