Is the petition a kickstarter? does the petition bring in ANY amount of funding for SU?
It doesn't. petitions are worthless. Do people honestly think the executives at Cartoon Network are oblivious to SU's popularity?
They aren't. if Steven Universe gets cancelled after it's fifth season (very likely), it won't be because "Teen Titans Go! is cancer" or something stupid like that. Steven Universe will be cancelled because of the lack of TV viewing profits and excessive spending on the part of the Crewniverse. Basic Economics.
Steven Universe is a pretty beautiful looking and sounding show, but that doesn't come cheap- not at all. the animation budget is incredibly costly, and the celebrity voice actors suck up a ton of money too. Low ratings, Needlessly expensive- Pretty much the reason ZIM got cancelled. I'll admit, I'm part of the problem- I watch the leaked episodes online 'cause I have to work over 6:00 when the episode airs, and I'd rather not be spoiled ahead of time. and I'm fine with that. If the show ends, it's not the end of the world. Sugar pretty much confirmed most of the loose ends of the story will be wrapped up by season 5 anyways. if it ends, it ends, and no amount of petitioning will change that.
