My thoughts after finishing Key to the Phoenix Heart last night (after a good night's sleep):
1) The cast are excellent, especially Neo Hou and Ai Mi. Both of them nailed their roles and they have quite good chemistry ❤️! Merxat as Prince Ying (Eagle Lord) also gave a good performance, though he does not have many scenes. Other supporting cast did quite well too 👍.
2) I like that the drama's pacing is consistent from start to finish; even the last 4 episodes are properly spaced out and not rushed 💖.
3) The plot twists kept me engaged throughout the drama. Even the extra clip after episode 28's ending theme gave a twist that made sense. I do have a question on one plot point but I think I'll rewatch that part, or ask around later 😄.
4) I appreciate the fight scenes; they are well-choreographed, e.g., XWY fighting with a red clothe as blindfold.
5) I love the ending! I'm glad it's very clear and not vague/open-ended.
6) I love the OST, which is very fitting for the drama. Neo Hou's opening theme and his duet with Zhang Bi Chen are excellent 💯.
I enjoyed this drama and it's a very good watch overall!
