Blood of Youth offers to the viewers, can't blame the high rating of 9.7 stars when many have watched less than episodes and given 10 stars. I'm reviewing this drama after completing watching the 40 episodes. Here's my rating and thoughts:

Plot: 9/10 ? Apparently this drama has it's twists and turns and keeps driving the viewer to watch till the end. Things rounded off well, viewers can see the ML is a stubborn man who makes his own decisions and it's this ending which makes them to crave more.

Characters: 6/10 ? This rating is for the ML, Xiao Se. I liked that he was this confident man who strategically worked towards his goals. What I didn't like was that in the martial arts world, the ML barely fought, even when he was treated of his injury, he continued to feebly (not my but Lei's words) wrap his hands in his long sleeves and never practiced. Of course I rolled my eyes when a shaft user, all of a sudden wants to own the tianzhan sword.
Other MLs did justice to their roles, Wuxin and Lei kept me going.
I can't say anything about the FL when she's basically treated as a side character in the whole drama.

Comedy: 9/10 ? Yes this drama will make you laugh, especially Wuxin and General when he first meets his future son in law, Lei.

Romance: 0/10 ? seriously if the director and scriptwriter chose to focus more on the fight scenes, then romance shouldn't have been added at all, however, couples were formed with zero thought to romance. First of all, Xiao Se's pairing with Quinlou wasn't great, zero on-screen chemistry, no moments between the leads happened.

Screen effects/fight scenes: 10/10 ? Amazing CGI during fight scenes is the best of this drama. Hats off ?

Background music: 5/10 ? Introductory music gave an okay feel but throughout the drama it lacked the goosebumps moments music when a great action happened.

So overall it's a good drama worth watching.
