City Hunter is good acting, good action, good story but when it comes to Healer it is better acting, better action, better story.
The female lead is same in both drama's although her character is more thorough and defined in Healer than in City Hunter.
The romance in Healer definitely overpowers the romance in City Hunter. the adaption is better as well.
In similarities, is the good guy second leads and the overall action.
If you liked City Hunter, Healer will swoon you :)
