It's bad in terms of, nothing was explained and everything happened all too fast w/o a background info. As to why was Youko's egg chosen, what was the purpose of taking her egg and stuff, and why was the way to retrieve the egg was to have intercourse. I think the logic of the story was flawed. But hey, it's sci-fi. And although I think it's bad, I still like it anyway (very oxymoronic).
But, well to each his own.
