It's not that Earthchild is bad. That's not quite true. Earthchild has love and heart in it. But the plot feels rushed to the point that each chapter could be its own massive story arc or even manga series of its own.
Contrived and convenient excuses allow for breakneck development that honestly should not happen that fast. Overall, the story can't breathe, and it feels like an awkward mishmash of different tropes or storylines that the author wanted to write, but instead of making them separate they just shoved it all in one. Or perhaps the author is afraid the manga will be axed and wants to get through things quickly.
Seeing how short Earthchild is now, I'd recommend giving it a try (*EDIT: this review was written as of chapter 3 out of 27). The first chapter alone felt like a solid 8/10 for me that I'd want others to read, but with each subsequent chapter, the quality dips.
I feel tempted to just pretend it IS a oneshot, and that's not a good thing.
