This drama has quite an interesting concept but somethings aren't explained properly. It also leaves you hanging at times.It has definitely got that anime feel to it but you some manga are not able to suck you into their world and this is what this drama did. It wasn't addictive. The main male lead's power wasn't given the importance it should have been given. The aim or goal of the organizations mentioned in the drama isn't made clear. What jellies are actually that answer is still as clear as mud. Are jellies just their greed or are they spirits or regrets?
So, ya you can give it a try but it may disappoint you a bit if you are looking for 'blow your mind' action.
