Pulled a SatAM
You see a great season finale, it ends on a cliffhanger leading to a new season, and BAM! Cancelled!
This trope would list the many different movie franchises, tv shows, web series, and whatnot that ended on a huge cliffhanger, usually after 1 or 2 seasons, much like Sonic Sat AM. This would include series such as Sonic Sat AM (The trope namer), The Hard Times of RJ Berger (almost identical to how Sat AM ended), Kyle XJ, and any others I have not mentioned. Unlike Left Hanging, it would only focus on series that had cliffhangers as a series finale.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
