Interesting
Like you said in a former response, there is indeed not much explained in this entire series. We still do not really know why there is a big hole in Graham's house that seems to lead to another dimension. What that other dimension exactly was is not explained either. And I don't know what Bahamut is doing on the moon. I can't remember that ever happening in one of your former flashes, I guess it might be explained later.
Anyway, I suppose this series was just silly randomness after all. It doesn't even give answers to questions that were posed in the first episode. But I see this series' ending immediately starts a new series. That is an interesting idea that I haven't seen that often before. Usually there is a series finale and then sometimes a (crappy) sequel series, but this finale just seemed like a middle episode. I'm quite interested in how this story continues.
Overall 5 out of 10, 2 out of 5. Not such a great episode or a good finale, but it had an interesting idea behind it.
