I've just finished and I have to say, it's one of those shows that has sucked me in while simultaneously annoying me intensely! 
. There's clearly an inexperienced/less talented writing team so weird gaps or odd conversations that just don't ring true, which on some episodes where particularly annoying. Plus....
Not really a spoiler as such but sort of so if you haven't finished, you might not want to know (although doesn't give actual details).....
The fact that NOTHING is resolved by the end of the first season. Literally NOTHING. A few revelations but nothing that actually intrinsically moves the story on?
Possibly just another sign of poor writing for a production with a somewhat limited budget and as it's got a season 2, it's possible they've decided it's worth investing in and will do more with but.... ARGH it's annoying!
