Spy is a spy drama (lol) entirely centered around the family of Kim Jaejoong's character. If you're looking for a spy drama that covers multiple plot, this is not really for you. A lot of people have found that this drama is boring, but I actually liked it a lot. Of course the story is a bit predictable, and it gets slower and repetitive towards the middle, but otherwise I thought it was nice. I even found myself thinking in the middle of the drama "hey... Why are there not more episodes !? u_u" but then the ending came fast but was maybe too long. They should've done the drama with more length or the same length, but the ending more... Compacted? I thought towards the ends that there was an episode too much, but however it was still ok. A few things were quite cliché too (and why the hell is it always the same situations when the North is included? o_o sometimes spy drama look like propaganda but well, I'm not Korean, I don't really now what happens there^^ Acting: Whoaaaah... What a great cast. I actually decided to watch this because everyone liked the cast, and I wasn't disappointed. Kim Jaejoong was perfect for this role, and you could see every change of emotions in his eyes. The other were really good and fitted their role. Kudos to the mother too, although I thought her character building was a bit bizarre- but that's because of the writers I guess Music: well, I didn't pay much attention- there was one good OST but I don't remember any other, so it must have been normal. But there was a music in the last episode that I liked a lot and that fitted the atmosphere. Rewatch value: well... I don't know. I probably won't rewatch it soon, or one or two episodes that I have liked a lot. Maybe in a few month I'll watch it again- even if it'd be for the cast hehe Overall: 8. Honestly the story is a bit cliché and the end is too slow, but otherwise it was ok. Acting perfect, music ok. If you like action-thriller-drama with a bit of romance (and family love, lol) this is for you!
