First let me start by saying I really appreciate there being an English version to watch. It's hard to watch subtitles for an extended period of time. I wish more foreign films would offer this option. I'd bet a lot more English speakers would watch the show providing they know it's an option. I just happened to try to watch it and thought I would have to deal with subtitles. What a pleasant surprise to find out that I do not. I am a lover of sci-fi so this is right up my alley. I just started watching the series yesterday and it has caught my interest. I am enjoying watching it. It's got a medium action flow to it. If you like sci-fi mystery then this is the show for you.
