This is a masterpiece. The story in itself beautifully written. The characters are well rounded, even the supporting characters' story-line are well developed. Coupled with perfect casting, you couldn't help but love the characters. Even for the villains, you could get their motivation and you'd get why they would act in a certain way (not in the sense that their actions were justified but because it's in their personality, "that's who they are"). The acting was solid. I loved how the director used subtle gestures and actions to convey the emotion of the characters like how he would zoom in on trembling hands to show anxiousness. The score was also great. It's not in your face like others in which you'd know that something is about to happen because of the music. It helped elevate the scene. My personal favorite is the humming version of Aging of Beauty.
I could talk about this all day but there is no better judge than yourself so go watch it. The pilot was good, you might be overwhelmed with the number of charters introduced in the first episode but you'll eventually get a hang of it. By the second episode, I was already hooked with the story and invested on the characters. If you are still not convinced, at least give this a shot till episode 12. By then if your still not invested then i don't know what to say anymore. :))
