This show is very reminiscent of Lost. It's got the individual character stories per episode and many mysteries and backgrounds to unfold. It even ends with, you guessed it , a hatch and bunker.....and a hell of a question mark to reel you in and make you scream with frustration when the credits roll.
It has English subtitles but it also has English voice over for each character. Half the time I was reading the subtitles and half the time I was just listening. There's always some factual given take with stories like this but I am hooked. I hope they don't wait another year or two to bring out the second season or the show get cancelled. I hope more English-speaking people will give the show a shot because it is fantastic.
