This type of stuff just makes you want to stop checking for modern animated series. It seems like nearly all of them get the rug pulled out randomly. I really wish they just planned 2 or 3 season arcs with CONSISTENT scheduling and left it there. At least then you'd know what you were getting into and there'd be none of this "OH WELL SHOW'S CANCELED BECAUSE qiugbfoubq9wbfioqwbfi"
Ugh.
Just wanted to say this is where, even in this day and age, the anime industry often has it over American animation.
It's pretty much stock-standard to plan a 26 episode series with an arc from beginning to end, and a definite conclusion. Some shows do have hooks built in, so that if popular another 26 episode series can be produced.
Other shows are planned and purchased for a presumed 51 episode run. Again, there's a framework so as to not leave the story hanging. Though admittedly, some truly tanked shows do get cancelled before they finish.
American animation has gotten far better in the area of dramatic shows in recent years (Tron Uprising was downright amazing.) But things are still planned, and written, as if it is hoped the shows continue to get good ratings and run perpetually. Even when shows have arcs as is becoming common, the arcs don't reach full conclusion at the end of a season.
I don't know whose fault this is. Are the show runners and writers still oblivious to the strong probability their show won't make it? Does the network insist that the show remain completely open ended in order to hook the audience into coming back just in case the show is renewed?
All I know is that it's becoming a major turn-off. I've stopped watching American TV dramas (live action) because almost all of them will get canned after 1 season, and sometimes half a season. Especially because it's still very common in a post-Lost world to base the show's premise around a giant mystery and a long-form arc to try and hook the audience. Except the show is rarely successful and is killed off shortly.
