This show is giving me The Society (was cancelled), Lost, and Dark vibes. It seems like a mixture of these three tv series. Some errors can be easily noticed from this whole past and present concept through a gigantic sinkhole, significantly how they "all" fall through it and how just some of them end up, and many other situations. I'm trying to ignore it because it is fiction (sci-fi, with normal human beings with no kind of superpower), but it is pretty hard; it still should make things straight in whatever theory they decided to go along with. And without being said, most of these characters are very annoying; most of them lack common sense. I don't hate it, but I have seen the entire season, and it could be better. Also, someone needs to have a word with the production designer (especially the make-up artist and hairdresser). And, try to get the geography and the ecosystem right; millenniums have passed.
