While the base story had such a good scope it was tainted with Bad direction and acting.
The presentation in the series is very illogical. Even after a long duration the cast never ages.
Because of the base story, the series is worth watching but you need to be very open and keep your brain aside while watching it.

Old review from before it was completed:-
My rating for this series keeps on dropping as I watch the new episodes. The acting is getting worse for all the actors!. Even the guest characters do a bad job at acting and it doesn't help that the script is so poorly written and not structured properly.

The base story is so good but just because its not presented properly, the series isn't highly rated and popular.
Slow-paced, bad acting, direction and illogical script at many scenes took the scope out of such a good base story.

The only thing I like about the series is the base story, that there is a grim reaper whose job is to take souls to the afterlife and a doctor who tries to save lives.
The script has so many plot holes that it either confuses me or I lose focus in it. It doesn't help that the series is slow-paced.
A good scope of improvement is there in the acting, the main and the secondary leads have problems with the correct expressions for different types of scenes.
