I have been searching for these series the whole day and after I finally found a complete set to have a good night watch, I was disappointed. From the first episode the story is somewhat forced and tense, it doesn't flow naturally. Coupled with moments of inadequate character behavior it becomes annoying up to the point when you start questioning the reasons they exist there at all. I could swallow poor storytelling if these series were short, say 1 OVA. But 26 episodes is enough space and time to tell the story decently. Yet, from the start I kept myself asking: WTF? And the sinkingship start was so promising... However, the makers were unable to keep the mysterious part to the declared mystery. My sense of wonder was stolen.

I won't drop and finish watching this, but I doubt it will get any better after 2 episodes, where the main cast was introduced (and I don't care about any of them flat folks, yes).
