I normally rate a show based on how much i was entertained by it. thus yes i do end up overlooking some flaws.

during the whole 36 episodes, you got the feeling that direction was different, editing was done by different groups and so many things which sometimes made so many episodes have a unique feeling. Epi1-15 had a feeling and flow, then in between another feeling, and post 30 there is another essence in the show. i will definitely recommend this show. It has another flavor as compared to many shows i watched.
Good points; all the actors were good, be it the main ones or secondary ones. ML doesnt turn 100% evil, FL 99.9% never distrusted the ML... I think music was something i liked the most in this show, and the ML's clothes especially when he was in demonic state were so pretty,.

Bad:
not sure to write it as bad or not, but i read about all the production issues this show faced. hence there was many scenes which were badly edited, a few important scenes never given at all (you'd understand if you watch the show :))

rewatch value: yes at least a few scenes are so beautifully done.

Watch this show for the actors, they did a brilliant job but unfortunately other issues impacted in general the outcome which was brought to us. But overall a good watch.

also after watching the show completely, i got the feeling that they wanted to deliver something really good here. because some scenes were indeed topnotch, but unfortunately could not.
