I have to say, S3 is SOO much better than the previous 2 seasons in my opinion. The animation style change a lot and the fight scenes are so cool and fluid!
S3 is only 8 episodes long and the MC didn't come into the story until episode 3. It mostly focuses on Wang Ye, a guy from S2 when the Chulan had to fight in the tournament, and his issues. The plot for S3 is fairly simple and doesn't really add to the overall that's been building up from the first season. Esp if you have no interest in Ouya. There are some good fight scenes here and funny moments between Chulan, Zhuge Qing and Wang Ye which is nice cause I like to see them interact outside of battles and such.
Other than that, S3 is quite forgettable and simple. However, I enjoyed it anyway with the animation style, battle scenes and Chulan showing that he's not just a shameless fool but a smart, shameless fool.
