pretty much the only show I miss a lot that got cancelled is who's line is it anyway?, but there are a bunch of shows that have changed so radically from what they were when I watched them, that you can practically consider them cancellations and revamps. Main example: fairly odd parents. That show was awesome when I watched it (and Timmys voice is Tara Strong. How's that for epic?)but now its literally terrible in every way. It makes me miss when cartoons were good... (mlp an obvious exception)
Not cancelled, just ended: Avatar, The Last Airbender. Ooh, the toonami block was good. Disappointed it had to end.
Toonami revolved around 95% of what I watched on TV. Cartoon Network used to be amazing back in the day. Now...? Heh, yeah no thanks.
Yep, I was a big fan of Gundam and Samurai Jack. Now this is one of the few animated shows I can watch.
