This is my first review, I couldn't just keep quiet after watching this amazing movie so here I am! Story: This story is so unique and beautiful, I've never seen anything so creative. In the beginning, being in a relationship with someone that has a different face and body everyday sounds a little bit weird and also a little bit fun, but as the story and their relationship progresses you can really see the real struggles that these two have to face. Yi-soo's inner battle over this relationship is conveyed really well and you can really experience her pain with her over the fact that she will never be able to remember her lover's face. This story breaks down all the problems that come with having a relationship, but shows that love can conquer all and that it's not what's on the outside that matters but what's on the inside that really counts which is a lesson well taught in this movie. The only thing I disliked about the plot is the fact that Yi-soo's "sickness" that she gets isn't really explained all that well and I felt a bit confused as to why she was experiencing some symptoms. Another part of the story that I didn't understand that well is Woo Jin's Parents' Story, essentially this ties in with Yi-soo's condition so that whole part was just a little fuzzy for me and lacked the clarification I needed to fully understand Woo Jin's condition, but other than that everything else is explained and conveyed really well. Acting/Cast: I gave this a 10 mainly because Han Hyo-Joo does such an amazing job as the lead female. It's already hard as it is to make an on screen relationship look believable, but to do so with 20+ co-stars is amazing. Not only did she have to get used to working with practically different co-stars in each scene, but to also act in-love with each and every one of them no matter their age, gender or looks...I really tip my hat off to her. Not only was her acting amazing, but it was also quite fun to see famous actors here and there as well. Music: I loved the music, it really fitted well with the theme and cinematography of the movie, it just gives this movie the extra bump that makes it perfect. I liked the fact that they went with a more classical, acoustic feel to the music, it really ties everything together and makes you feel at ease while watching the movie. Cinematography: I just had to add this one in here. I was very impressed with how the movie was filmed. The scenes and shots were beautiful, the tones that they used were soft and very fitting and overall it was just very professionally and beautifully made. I definitely recommend this to everyone, it's really a film that many types of people would enjoy and also makes you reflect a little bit on life and love and teaches you an important lesson in between.
