To be honest, the show isn't even bad. However the show has too many plot holes and too many frustrating bits with how the characters are not thinking smart. Yes they may have been written as not smart however, a person with an average IQ would definitely think better than how the actions are portrayed in the show.

The fighting is pretty mediocre and can be boring. You'd think if you had a immortal body you would train yourself.

The song is alright, I liked how they changed versions even though it probably is just one version that has different parts in the song. However it does really get annoying. I understand it's for the plot, but I don't know. To me the song connect situation doesn't make sense at all.

The time skip is super weird. I either forgot how long was the time skip mentioned or it was never mention properly. Like when did that thing happened?

The acting was fine, not the best but not bad at all. It was mostly neutral in the entire time of the show.
I still do not understand how they get the immortal body.. I payed attention the entire time and still didn't know. Only knew the situation between the male leads. Can someone please comment down the answer.

The cgi was great. One of the reasons I remained to watch. I knew the cgi was going to be good just from trailer.

uh.... The sex scene... I do like thirsty scenes however, it was placed seriously at the wrong time. Like they talking about the suspect and then boom, sex scene in front of the screen.

Overall: Too messy, can be enjoyable, many plot holes, no smart decisions, kind of mediocre. 7.0 or 7.5 fits this rating.
