I loved it and have seen it 3 times. It rates near the top on China's Douban list and many see it as a masterpiece. The high rating is no mistake, it is a wonderful, deep, and intriguing drama. But it really depends on what you like. Some people like simple love stories or comedies. This is neither.

Lots of reviews already but... I just wanted to add that there is an unofficial version of the end that was cut. If you haven't seen it, please do. ^^ You can find it on YouTube.

Since this has been heavily reviewed, I'll still put in my two cents. This is a near-perfect drama for me. Probably the best I've ever seen as far as story. The casting and acting are top-notch. This is the second time watching it and no doubt, I'll re-watch it again. High re-watch value due to the complexity of the story. It has such a phenomenal story, and the casting, acting, and chemistry between all the actors/actresses are also top-notch. The genius of Mei Changsu is an intriguing and beautiful thing to watch unfold.
