If you are like me and very late to watch this series - let me say that I had read the endless reviews about the sad ending before I decided to watch it. So I watched 19 episodes preparing myself for the worst - trying to keep a level head about what will come. I ended up watching all the episodes with a diehard addiction. This series sucks you in, grabs you and then keeps you hanging on until the end. The actors have done a fantastic job, the plot, chemistry, action and romance - all are there. Including the sad ending, which somehow ends up being worse than what was probably anyone's worst scenario.
It is not perfect, and some parts feel a bit long - others are just painful - but it is definitely worth a watch.
