When my friend first raved about this drama, I was very hesitant. I usually avoid anything to do with sci- fi or aliens. But after she kept nagging at me to watch I decided to try it. Eventually it became one of my favourite dramas ever! Story wise the drama did have some cliches but the writers did know how to re-write the cliches in a way that was new and fresh using humour and the unique concept of falling in love with an alien. What sold it for me were the actors, they were refreshing and made each of the characters have a lot of depth. Before this drama I had only ever seen Kim Soo Hyun as the country boy Samdong in Dream High and thought I would find it hard to see him as a manly, cold but good looking alien. Watching this drama made me forget his previous role and his character drew me in. Jun Ji Hyun played her role as a hallyu star in a way which made her seem absolutely crazy but still relatable and loveable. Whilst some may think that her character was too over the top, you have to remember that the drama is about an alien falling in love with a human. So yes there are other aspects that will make it slightly 'out there' but the writers worked hard to still make the realistic and relatable. Initially I did think that Jun Ji Hyun and Kim Soo Hyun did look slightly strange together, like an aunt and her nephew. But the chemistry won me over and pretty soon I was rooting the two on! :) Even the villain was great! Just the right among of evil without going too overboard. Shin Sung Rok definitely made me hate him in a good way and I was impressed with his acting skills. One thing I will say is that Yoo In Naa's character did not have as much of a development that I would have liked. Music wise, there was nothing too special or memorable. The songs were nice to listen to at the time but I wouldn't find myself listening to the OST again and again. As for whether I would rematch this again… I already have… 3 times! The humour, the characters and the romance definitely are the things that always make me rematch this drama. This drama is always one that I miss and get a 'drama heartache' because I love it so much. Watch it guys! You won't regret it!
