I have finished watching this series 2 months ago and re-watched it 1 time. This is one of the Chinese drama that can make me engaged, addictive! Yes of course there's flaws, but not that significant to rate the drama low.
And after watching the series I also read the novel (haven't finished)

So so far this is the justification to give high ratings for Love and Redemption:
Story : Even though there's some difference between the novel and the drama, but the main take away message from both drama and novel is still there, which is unconditional love. Admire Si Feng's persistent love for 10 live times, and finally he can harvest his hard labor and got Xuan Ji love in return. This teaches us as human that to love is to give not expecting any return, today human society need to go back to this basic principle of love. (not self-centered, consider others). It just to me there's too many story about Ming Yan and Ling Long which is unnecessary and not really related to the whole story, maybe just wanted to give more screen time to the actor / actress? But this make me deduct the point from the story.

Acting : I love the acting of the casts (except for Ming Yan, I found his acting is terrible and annoying). But the excellent acting from the rest, especially the main female and male lead can cover that.
Female Lead : you can see clearly the character development of Xuan Ji and it's portrayed very well by Yuan Bing Yan. From the innocent Xuan Ji to the Killing God of War. Portraying so many characters in one series is not easy, but she did very well here, and the acting is not overacting it's natural.
Male Lead : actually there's not much challenge to portray Si Feng, honesty this character quite similar with the one Cheng Yi played on Noble Aspiration (aside to the love story). Thumbs up for all the spitting blood and crying scene, oh he did cried a lot and I believe it's not easy for a guy to cry. And the cry was not merely tears, but with red eyes (so for sure not using fake tears). And of course the holding hand scene with Luo Huo Ji Du, he act very well there.

Music : Nice music, and very well placed throughout the series.

The characters that I like from this series: Teng She

So overall I recommend to watch Love and Redemption and hope you also enjoy it like me
