Well, Thank You is a simple plot portrayed beautifully in 16 hours. The topic is relevent even today on how a person with AIDS will be viewed by the society. Instead of going on a full sorrow mode, the drama mixes up with good romance and comedy. Each character is mentionable . The child actress is very talented and promising . The grandpa character is also one memorable.
Personally, I was not into pre 2010 drama as I'm afraid the plot will be different from my taste. But this drama changed my view. It's surely an underrated drama without all the post 2010 nuisance. Yes, it has cliches but bearable. Gong yo Jin is superb and I liked her acting skills.
I'm not sure if I will recommend this drama but if you like Coffee Prince, you can go for it.
