Overall it hooked me from the beginning till the end, the story and the acting is great, immersing you into the story and making you love or hate some characters.
A big BUT, though, I can't get over the awful and quite repetitive soundtrack, which makes almost every scene more dramatic than it should be. There's no need for a dramatic church-like chorus singing to a scene where they eat barbecue, really - the same song can be heard at least ten times in each episode.
Otherwise, nothing else to reproach.
