Story 10/10 Wow, so many plot twists... There is such an emotional and psychological depth to this drama... The writing is fantastic and I didn't find myself skipping scenes like I usually do... MARS is definitely a mature drama that will take you on an emotional rollercoaster.. Although it is heavy, there are many cute, funny scenes to lighten to mood, too. The ending is complete and there are no loose ends! Acting/Cast 10/10 All of the actors were amazing, but Barbie and Vic especially stood out to me. First, their relationship is so believable. They have such great chemistry together. Coming from someone who normally watches Kdrama, it was so refreshing to see the main couple so comfortable together (even showing affection for one another in a non-awkward way, lol). Vic is especially amazed me... I don't want to give away any plot points, so I won't say more! :) Music 10/10 WOW! I usually never pay attention to music of a drama... but this drama's music is absolutely breathtaking. Especially Ling (Zero)... I liked it so much I'm learning to play it on my guitar and piano... Look up the english translations to the songs, because they have such meaning and add depth to the story! Rewatch Value 6/10 Ok, I never really rewatch dramas... So this is just a personal opinion... I know a LOT of people have rewatched this drama, so maybe you'll want to watch it again... Because it IS one of THE best dramas I've watched. Overall 10/10 Please watch this drama; I promise you won't regret it!
