I had basically no idea what this drama was about when I started it, and ended up having a fun time with it, even if it's truly not the best. In my opinion, the main problems are that the writers had a hard time balancing the quirky idol plot with the Evil One plot. They underdeveloped both plotlines and ended up not giving the viewers enough of either. If they'd managed to find a better balance with incorporating the Evil One stuff into the idol plot, this would've been better. Also, they should've cut way down on the second hand embarrassment of Rembrary not knowing what he's doing as an idol. It was funny at times, but I started to skip through a lot of that because I can't handle second hand embarrassment very well.
The very best part for me was Rembrary, Dal, and the Grim Reaper trio. They were so much fun all together!
