Yeah...I'm probably using the term as "the show didn't fizzle out naturally (did well ratings wise) and was a victim of the Disney buyout"...Though you are definitely right on both counts.
I have a feeling because Warner Bros owns all of those IPs Cartoon Network puts them on the backburner to promote their own properties...but that's not really the case as they rely on TTGo so much who is also owned by WB. I think they will sabotage anything that isn't a comedy... However I think that may be a problem with Western Animation in general on Network TV. The days of "toyetic" action cartoons are not as prevalent as they used to be.
