I've spent my 4 days off from work watching this drama & finally it has come to an end. I still have an alien thingy hang-over. All 9's. Story - Its something unique for me because I've seen all sort of movies about vampires and werewolves but not much for alien that really allure me. However, I didn't feel that much excited in some episodes. There are dramas that I've watched that if not because I have to, I won't stop. Like I'm always looking forward for the next episode. This one felt short in some Episodes but I so love that last 5 episodes. Acting - for Jun Ji Hyun, I felt like her acting here is same-same with how she portrayed her character in My Sassy Girl. But still, its really good. Specially in the comedy part, she brought it all out. Kim Soo Hyun is sometimes stiff. Same expression most of the time. And I don't think its because of his character coz I felt the same in Moon embraces the Sun. Music - ohhh I love 2 of the songs (My Destiny & Hello, Goodbye). I wish they've used it more often. Rewatch Value - it will soon be aired in our country and I will definitely watch it again. Overall - its great and something that its worth watching. For sure!
