In my opinion MARS is a really hard drama to watch...if you want to watch something light right now please don't bother with this one.MARS is my favorite drama out there and I think that it suceded in overlaping even the korean dramas and japanase ones. Story: It's the most developed one that I've seen until today.It's the full package of romance, action, drama and mistery.It made me fall off my chair from laughing sometimes, but on the other hand it made me use so many many tissues most of the time.Is a very serious story which touches ideas and problems that were never touched once before. Acting/Cast: What can I say about this....I really loved the chemestry between Barbie Hsu and Vic Zhou since Meteor Garden, but here was really outstanding.I love Brbie Hsu..she is my favorite TW actress, not only she is beautiful but also has great talent.It always seemed to me that she and Vic were soulmates because of their interection and underestanding with each other.The characters were so well portraid that it made the story come alive. Music: It was really beautiful.Trust me..I don't like TW music..I really find it annoying most of the time but this one was so beautiful that I don't know what to say.The song Ling/Zero described so well the drama that only listenig to it brought my tears. Rewatch Value: I really don't rewatch dramas often because it's boring for me to know what happens next and so on...but I would definetely rewatch this one..I don't know why but only rewatching some scenes or listenig to the songs makes me shed tears of sadness.For me this drama is one in 5 years or so. Overall: For me a drama can get 10 points only if it can remain in my head for a long period of time and it can make me compare it with others.This one succeded in this and it also made me to open my eyes and to be happy for what I have because their are many more people more unhappy and with more problems out there than me. So I think that when you are in a state of mind of watching a REAL love story not a "fantazy" one you should give this try and let it get into your heart
