Although this series has horror elements, it doesn't go all out to be scary. I believe it will suit those who prefer milder horror. There's actually nothing very unique about the horror elements -- it's largely the same old tactics like scary make-up and sudden appearances. Some elements are not really explained as far as I can remember, such as the eye symbol and the numerous eyes on the villain's back. The demon's appearance in the last episode actually looks a little comical, and I'm not sure why it doesn't just keep on using the face of the man it has possessed given that it is still in the body. I find the humorous moments in the series more entertaining, than the horror. This may be a good thing as the series has many elements of a crowd pleaser, from horror to humor and romance and touching drama. Too much horror may put off some people.

Some narrative threads could have been better developed. The male protagonist's mother is supposed to have created two bracelets, one to protect him and another one to kill the demon. However, it seems to need additional explanation. If the mother is such a powerful exorcist, she could have killed the demon herself. (Instead, she is killed by the demon when the protagonist is still a kid.) The bracelet is kept by her husband, it seems, who then seems to be on the run from the demon because he doesn't want the demon to land his hands on the bracelet that can kill him. Dude, maybe you should put the bracelet to good use for once? It appears that the demon has possessed a human being and this prevents the bracelet from having an effect on him, so the characters can only try to avoid the demon while he is in the man's body. Yet, we also see that in the final episode, it isn't altogether impossible to force the demon out of the man and kill him with the bracelet. So perhaps all the evildoings of the demon could have been prevented.

Despite its flaw, the series does manage to be rather good entertainment. Numwan, the villain's girlfriend, can be an intriguing character even though it seems that the writers do not really know what to do with her in the second half of the series.Junior (one of the guys who is aspiring to find fame by catching a ghost on camera) can be rather annoying but he is annoying in the sense that one would not want to meet someone like him in real life, but it can be fun watching the nonsense he is up to in a series.
