I enjoyed this one. I thought the world-building was well done and I liked the theme of a group of young people coming together as a team. I look forward to seeing Wu Xuan Yi in more works--she was adorable as a feisty rabbit in Douluo continent and Xiao Zhan did a good job playing an idealistic young 'lad' who had some growing to do. I also liked the hate-to-love relationship of Dai Mu Bai and Zhu Zhu Qing. The Headmaster was my favorite character--he was so hilarious, especially his obsession over money. Seeing Calvin Chen in his early forties in DLC and then watching him in KO One was a bit of a shock--should have done those in reverse order (though I'd really only watched KO One for Jiro Wang).
There was some illogic and inconsistency as there is in all dramas (for example, why was there no audience during the final competition--wasn't it kinda of a big deal!?). The evil characters' motives sometimes seemed a bit fuzzy. I also felt bad for all the animals they were always killing off--though that was kind of the theme and leads' goal was to minimize the need for that type of killing.
I'm looking forward to Season 2 (hopefully there is one, given the ending). I would recommend it to those looking for a Xuanhuan version of Harry Potter & the like. :D
PS. The music was bizarre. I read here on MDL that it was due to copyright issues so they had to use different music than what the original played in China. However, they should have picked something other than 1970's porn music (not that I know from personal experience, but that's what I imagine it would sound like. ;P)
