Ugh.. it's so difficult to finish, I tried believe me, but i fell asleep several times before episode 8 finished. I know I'm close to the end but i was watching it since everyone said the last episodes were so good. I was disappointed :(
Probably the quality of everything, some of the acting was forced, special effects were bad, the plot is a bit interesting but it was predictable. But hey that's just what i think, it seems everyone else is enjoying it :).
EDIT: Just finished it in one day, looking forward to next season! I can't wait!!
