Why doesn't Ginormica have more fans?

My reasoning is she isn't a full enough character. She, and the other monsters, have great potential to be better heros or just well liked characters if they had more to do. What I wanna see it, not another halloween special- but a series. Not a saturday morning one, or something like the Penguins of Madagascar or KungfuPanda (both painfully bad); just a mini series.
On tv periodically, long enough to give a story- something to catch people's eye. A few shorts to give the Monsters some room to grow and be more than just their names.
