You should definitely watch it and ignore the rating.

Such an underated drama. I loved all the actors and the plot was really interesting. I think they portrated important themes along the way. They made a smooth transition between new actors that they added through out the show. It's also not too long so it doesn't put you in a slump. It was exciting and I was really looking forward for new episodes. I'm hoping that there will be a season 2, because i would surely watch it. The lead actor deserves more recognition. More people should watch it.
