Trakt for iOS
Works on iPhone and iPad.
This is clearly a well-budgeted and well-made show.
However, I was left feeling out of place with it constantly. Maybe it's my fault - I did watch it sporadically so I kept having to catch up with the thread of the story.
Nevertheless I just didn't connect with it and didn't feel the sense of danger that (I presume) I was supposed to feel.
The acting is fine and it's full of nice shots and cinematography. But it all felt very clinical - even with the subtitles (I find dubbing often puts me off) and left me baffled why I should care.
