I watch Chinese dramas for badass heroes/heroines who fight for the good and destroy the bad people who try to harm them. Not so with Fighter of the Destiny because the story lacks continuity in that the hero gets into a dire situation (usually bcos someone plotted against him) and then he's miraculously rescued after which he returns to normalcy without ever seeking retribution on those who attempted to kill him. At a point, it seemed like the whole world was out to get him and he just folded every single time.
It also didn't help that no one else in their clique had the intelligence to move things along. Loulou was always crying, pouting, or shouting for her Shifu, while thirty-six and the bear guy kept getting more stupid as the story progressed. Conversely, Chengsheng being the only one who could solve the riddles, heal with his blood, develop good fighting skills even if we barely saw him practice, and was primed to save the world...was just a tad bit too much.

Another negative aspect of the story is that I'm tired of the childhood-friends-to-adult-lovers pipeline in C dramas. I simply cannot watch another stupid story where kids are supposed to have fallen in love back when they were 5 or whatever. China has 1.4 billion people so even if we adjusted the population for the time period, it would still be in the millions and the likelihood of them reconnecting is infinitesimal. So, please, can writers please stop with this trope?

Lastly, despite not really liking the series, I have to give a shoutout to, Chen Su, the actress who played the Empress, as well as whoever styled her character because she was absolutely breathtaking.
